  • ListView in Android, handler for clicking item

    - by eljainc
    Hello, I have an activity in Android which uses a ListView. When I click on an item in the ListView, I would like to be able to determine which item was clicked. I have the following code: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); setContentView(R.layout.listr); //setupDB(); // populateList3(); ListView lv = (ListView) findViewById(R.id.ListView01); lv.setClickable(true); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(ListRecords.this,"Clicked!", Toast.LENGTH_LONG).show(); } }); } My XML code: xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/Linear03lr" android:layout_width="fill_parent" android:orientation="vertical" android:gravity="center" android:layout_height="fill_parent"> android:layout_width="wrap_content" android:layout_height="400dp" / <Button android:id="@+id/previousbutton" android:gravity="center_horizontal" android:layout_width = "fill_parent" android:layout_height = "fill_parent" android:text="Previous Menu"/> </LinearLayout> What am I missing here to be able to intercept clicks on the Listview? Thanks

  • KO3: How to deal with stylesheets and scriptfiles

    - by Svish
    I'm using Kohana 3 and it's template controller. My main site template controller currently looks something like this: <?php defined('SYSPATH') or die('No direct script access.'); abstract class Controller_SiteTemplate extends Controller_Template { public function before() { parent::before(); // Initialize default template variables $this->template->styles = Kohana::config('site.styles'); $this->template->scripts = Kohana::config('site.scripts'); $this->template->title = ''; $this->template->content = ''; } } And then in my template view I do: <?php # Styles foreach($styles as $file => $media) echo HTML::style($file, array('media' => $media)).PHP_EOL ?> <?php # Scripts foreach($scripts as $file) echo HTML::script($file).PHP_EOL ?> This works alright. The problem is that it requires the style- and script files to be added in the controller, which shouldn't really have to care about those. It also makes it a hassle if the views are done by someone else than me since they would have to fool around with the controller just to add a new stylesheet or a new script file. How can this be done in a better way? Just to clearify, what I am wondering is how to deal with page specific stylesheets and scripts. The default and site-wide ones I have no problem with fetching from a config file or just put directly in the template view. My issue is how to add custom ones for specific pages in a good way.

  • JQuery modal box form validation

    - by vikitor
    Hi, I was using a view to create an object for my specific project, but now I have to adapt this to another requirements, such as the creation of this object must be integrated in the creation of another one. The thing is, that this object must be created before starting to create the other one, and the way of doing it will be poping up a modal dialog box with JQuery with the form to create it. I've got to adapt the creation and it works fine, except for the validation messages. It is made in the controller like : if (not.NotName.Trim().Length == 0) { ModelState.AddModelError("NotName", "Name is required"); } if (_notification.checkIfExists(not.NotName, not.NotRecID)) { ModelState.AddModelError("NotName", "Notification already exists"); } And before with a normal view it worked fine, but now I'm not able to get the validation messages as I did. How can you get this validation messages thrown by the controller in the Modal Box? Because now when I made a mistake on purpose in the form in order to get the error it doesn't appear. I've seen the error is displayed in the site, because I've seen it on firebug, but it doesn't appear in my model box. How can I retrieve this errors? Do you know any tutorial that could help me with this? Thank you

  • My list item's child label elements disappear in IE on accordion menu opening

    - by Scott B
    I've got an app that's working pretty flawlessly in Chrome and FF, however, when I view it in IE, all is well until I click on a header element to activate it (jQuery accordion). What happens then is that I see a brief flash where the content is there, then suddenly the entire left column disappears. This column is generated by a floated label element with a class of ".left" as seen below... <ul class="menu collapsible"> <li class='expand sectionTitle'><a href='#'>General Settings</a> <ul class='acitem'> <li class="section"> <label class="left">This item if floated left with a defined width of 190px via css. This is the item that's disappearing after a brief display</label> <input class="input" value="input element here" /> <label class="description">This element has a margin-left:212px; set via css in order to be positioned to the right of the label element as if in an adjacent table cell. When I add a max-width property to this element, it disappears in IE too!</label> </li> </ul> </li> </ul> As you can see from the comments in the code above (for the two label elements) the description label disappears once I set a max-width on it (I don't have a max-width on the left label element, but it disappears nonetheless). The initial view of this UL menu is fine (note the expand class declaration which makes this part of the accordion open at startup. Its not until I click the "General Settings" to toggle it closed, then back open, that the left class elements disappear (and only in IE)

  • Rails: Can't set or update tag_list using a text field with acts_as_taggable_on

    - by Josh
    Hey everyone, I'm trying to add tagging to a rails photo gallery system I'm working on. It works from the back-end, but if I try to set or change it in the form view, it doesn't work. I added acts_as_taggable to the photo model and did the migrations. My gallery builder is programmed to add one tag automatically to each photo it creates. This works fine, just as if it were setting it for the console. However, I can't seem to set tags using a text_field in the photo form. Here's the code I added to my photo form: <p> <%= f.label :tag_list %><br /> <%= f.text_field :tag_list %> </p> Now, that's pretty trivial, and since :tag_list supports single-string comma-separated assignment (e.g. tag_list = "this, that, the other" #= ['this', 'that', 'the other']), I don't see why using a text field doesn't work. And to make even less sense, if a tag list has already been populated, the list will still show up in the text field when editing the photo. I just can't seem to commit any changes to the list. The documentation on their github page doesn't appear to give any information on how to set these values from the view. Any ideas? Oh, and I'm using the Rails 3 gem version.

  • Optimize a views drawing code

    - by xon1c
    Hi, in a simple drawing application I have a model which has a NSMutableArray curvedPaths holding all the lines the user has drawn. A line itself is also a NSMutableArray, containing the point objects. As I draw curved NSBezier paths, my point array has the following structure: linePoint, controlPoint, controlPoint, linePoint, controlPoint, controlPoint, etc... I thought having one array holding all the points plus control points would be more efficient than dealing with 2 or 3 different arrays. Obviously my view draws the paths it gets from the model, which leads to the actual question: Is there a way to optimize the following code (inside the view's drawRect method) in terms of speed? int lineCount = [[model curvedPaths] count]; // Go through paths for (int i=0; i < lineCount; i++) { // Get the Color NSColor *theColor = [model getColorOfPath:[[model curvedPaths] objectAtIndex:i]]; // Get the points NSArray *thePoints = [model getPointsOfPath:[[model curvedPaths] objectAtIndex:i]]; // Create a new path for performance reasons NSBezierPath *path = [[NSBezierPath alloc] init]; // Set the color [theColor set]; // Move to first point without drawing [path moveToPoint:[[thePoints objectAtIndex:0] myNSPoint]]; int pointCount = [thePoints count] - 3; // Go through points for (int j=0; j < pointCount; j+=3) { [path curveToPoint:[[thePoints objectAtIndex:j+3] myNSPoint] controlPoint1:[[thePoints objectAtIndex:j+1] myNSPoint] controlPoint2:[[thePoints objectAtIndex:j+2] myNSPoint]]; } // Draw the path [path stroke]; // Bye stuff [path release]; [theColor release]; } Thanks, xonic

  • Updating database row from model

    - by Jamie Dixon
    Hey everyone, I'm haing a few problems updating a row in my database using Linq2Sql. Inside of my model I have two methods for updating and saving from my controller, which in turn receives an updated model from my view. My model methods like like: public void Update(Activity activity) { _db.Activities.InsertOnSubmit(activity); } public void Save() { _db.SubmitChanges(); } and the code in my Controller likes like: [HttpPost] public ActionResult Edit(Activity activity) { if (ModelState.IsValid) { UpdateModel<Activity>(activity); _activitiesModel.Update(activity); _activitiesModel.Save(); } return View(activity); } The problem I'm having is that this code inserts a new entry into the database, even though the model item i'm inserting-on-submit contains a primary key field. I've also tried re-attaching the model object back to the data source but this throws an error because the item already exists. Any pointers in the right direction will be greatly appreciated. UPDATE: I'm using dependancy injection to instantiate my datacontext object as follows: IMyDataContext _db; public ActivitiesModel(IMyDataContext db) { _db = db; }

  • Cakephp, Route old google search results to new home page

    - by ion
    Hi there, I have created a new website for a company and I would like all the previous search engine results to be redirected. Since there were quite a few pages and most of them where using an id I would like to use something generic instead of re-routing all the old pages. My first thought was to do that: Router::connect('/*', array('controller' => 'pages', 'action' => 'display', 'home')); And put that at the very end of the routes.php file [since it is prioritized] so that all requests not validating with previous route actions would return true with this one and redirect to homepage. However this does not work. I'm pasting my routes.php file [since it is small] hoping that someone could give me a hint: Router::connect('/', array('controller' => 'pages', 'action' => 'display', 'home')); Router::connect('/company/*', array('controller' => 'articles', 'action' => 'view')); Router::connect('/contact/*', array('controller' => 'contacts', 'action' => 'view')); Router::connect('/lang/*', array('controller' => 'p28n', 'action' => 'change')); Router::connect('/eng/*', array('controller' => 'p28n', 'action' => 'shuntRequest', 'lang' => 'eng')); Router::connect('/gre/*', array('controller' => 'p28n', 'action' => 'shuntRequest', 'lang' => 'gre')); Router::parseExtensions('xml');

  • PHP what is faster to use

    - by user1631500
    What is faster / better to use? To put html into variables and print them later, or to just html print / echo print the content based on condition? EXAMPLE 1:(html into variables) if(!isset($_SESSION['daddy'])) { $var = "<span class='something'>Go here:<a href='#'>Click</a></span> <span class='something'>Go here:<a href='#'>Click</a></span>" } else { $one=$_SESSION["one"]; $two=$_SESSION["two"]; $three=$_SESSION["three"]; $var = You are cool enough to view the content; } echo $var; EXAMPLE 2:(print based on condition) if(!isset($_SESSION['daddy'])) { $var = 1; } else { $one=$_SESSION["one"]; $two=$_SESSION["two"]; $three=$_SESSION["three"]; $var = 0; } if ($var==1) { ?> <span class='something'>Go here:<a href='#'>Click</a></span> <span class='something'>Go here:<a href='#'>Click</a></span <?php } else { ?> You are cool enough to view the content. <?php } ?>

  • ASP.MVC 2 Model Data Persistance

    - by toccig
    I'm and MVC1 programmer, new to the MVC2. The data will not persist to the database in an edit scenario. Create works fine. Controller: // // POST: /Attendee/Edit/5 [Authorize(Roles = "Admin")] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Attendee attendee) { if (ModelState.IsValid) { UpdateModel(attendee, "Attendee"); repository.Save(); return RedirectToAction("Details", attendee); } else { return View(attendee); } } Model: [MetadataType(typeof(Attendee_Validation))] public partial class Attendee { } public class Attendee_Validation { [HiddenInput(DisplayValue = false)] public int attendee_id { get; set; } [HiddenInput(DisplayValue = false)] public int attendee_pin { get; set; } [Required(ErrorMessage = "* required")] [StringLength(50, ErrorMessage = "* Must be under 50 characters")] public string attendee_fname { get; set; } [StringLength(50, ErrorMessage = "* Must be under 50 characters")] public string attendee_mname { get; set; } } I tried to add [Bind(Exclude="attendee_id")] above the Class declaration, but then the value of the attendee_id attribute is set to '0'. View (Strongly-Typed): <% using (Html.BeginForm()) {%> ... <%=Html.Hidden("attendee_id", Model.attendee_id) %> ... <%=Html.SubmitButton("btnSubmit", "Save") %> <% } %> Basically, the repository.Save(); function seems to do nothing. I imagine it has something to do with a primary key constraint violation. But I'm not getting any errors from SQL Server. The application appears to runs fine, but the data is never persisted to the Database.

  • Iteration over a linq to sql query is very slow.

    - by devzero
    I have a view, AdvertView in my database, this view is a simple join between some tables (advert, customer, properties). Then I have a simple linq query to fetch all adverts for a customer: public IEnumerable<AdvertView> GetAdvertForCustomerID(int customerID) { var advertList = from advert in _dbContext.AdvertViews where advert.Customer_ID.Equals(customerID) select advert; return advertList; } I then wish to map this to modelItems for my MVC application: public List<AdvertModelItem> GetAdvertsByCustomer(int customerId) { List<AdvertModelItem> lstAdverts = new List<AdvertModelItem>(); List<AdvertView> adViews = _dataHandler.GetAdvertForCustomerID(customerId).ToList(); foreach(AdvertView adView in adViews) { lstAdverts.Add(_advertMapper.MapToModelClass(adView)); } return lstAdverts; } I was expecting to have some performance issues with the SQL, but the problem seems to be with the .ToList() function. I'm using ANTS performance profiler and it reports that the total runtime of the function is 1.400ms, and 850 of those is with the ToList(). So my question is, why does the tolist function take such a long time here?

  • Nested functions not allowed in drawrect problem

    I have a custom view onto which I draw some graphics from the drawrect function, which works fine. However I like to draw based on the contens of an array I pass on the the view just before I do a setNeedsDisplay. In the drawRect function I try to access the array but then I get a nested functions error which I do not understand.

  • Android - Take a photo, save it in app drawables and display it in an ImageButton

    - by Andres7X
    I have an Android app with an ImageButton. When user clicks on it, intent launches to show camera activity. When user capture the image, I'd like to save it in drawable folder of the app and display it in the same ImageButton clicked by the user, replacing the previous drawable image. I used the activity posted here: Capture Image from Camera and Display in Activity ...but when I capture an image, activity doesn't return to activity which contains ImageButton. Edit code is: public void manage_shop() { static final int CAMERA_REQUEST = 1888; [...] ImageView photo = (ImageView)findViewById(R.id.getimg); photo.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent camera = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(camera, CAMERA_REQUEST); } }); [...] } And onActivityResult(): protected void onActivityResult(int requestCode, int resultCode, Intent data) { ImageButton getimage = (ImageButton)findViewById(R.id.getimg); if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) { Bitmap getphoto = (Bitmap) data.getExtras().get("data"); getimage.setImageBitmap(getphoto); } } How can I also store the captured image in drawable folder?

  • [ASP.NET MVC] Run ajax scripts on page with navigating with ajax?

    - by Oskar Kjellin
    I got a bit of an issue in my ASP.NET MVC project. I have a chat div in the bottom right corner (like facebook), and of course I do not want this to reload when navigating to all my navigation is ajax. The problem I am facing is that I use the following code on the top of the view page: <script type="text/javascript"> $(document).ready(function() { $('#divTS').hide(); $('a#showTS').click(function() { $('#divTS').slideToggle(400); return false; }); }); </script> The problem is that this code is only loaded with ajax and does not seem to fire? I would like to run all scripts in the newly loaded view, just as if I hadn't navigated with ajax. I cannot put this in the site.master as it only loads once and then probably the divs I am trying to hide doesn't exist. Is there a good way to run scripts in the ajax-loaded div?

  • ndarray field names for both row and column?

    - by Graham Mitchell
    I'm a computer science teacher trying to create a little gradebook for myself using NumPy. But I think it would make my code easier to write if I could create an ndarray that uses field names for both the rows and columns. Here's what I've got so far: import numpy as np num_stud = 23 num_assign = 2 grades = np.zeros(num_stud, dtype=[('assign 1','i2'), ('assign 2','i2')]) #etc gv = grades.view(dtype='i2').reshape(num_stud,num_assign) So, if my first student gets a 97 on 'assign 1', I can write either of: grades[0]['assign 1'] = 97 gv[0][0] = 97 Also, I can do the following: np.mean( grades['assign 1'] ) # class average for assignment 1 np.sum( gv[0] ) # total points for student 1 This all works. But what I can't figure out how to do is use a student id number to refer to a particular student (assume that two of my students have student ids as shown): grades['123456']['assign 2'] = 95 grades['314159']['assign 2'] = 83 ...or maybe create a second view with the different field names? np.sum( gview2['314159'] ) # total points for the student with the given id I know that I could create a dict mapping student ids to indices, but that seems fragile and crufty, and I'm hoping there's a better way than: id2i = { '123456': 0, '314159': 1 } np.sum( gv[ id2i['314159'] ] ) I'm also willing to re-architect things if there's a cleaner design. I'm new to NumPy, and I haven't written much code yet, so starting over isn't out of the question if I'm Doing It Wrong. I am going to be needing to sum all the assignment points for over a hundred students once a day, as well as run standard deviations and other stats. Plus, I'll be waiting on the results, so I'd like it to run in only a couple of seconds. Thanks in advance for any suggestions.

  • Rendering a CGPDFPage into a UIImage

    - by James Antrobus
    I'm trying to render a CGPDFPage (selected from a CGPDFDocument) into a UIImage to display on a view. I have the following code in MonoTouch which gets me part way there. RectangleF PDFRectangle = new RectangleF(0, 0, UIScreen.MainScreen.Bounds.Width, UIScreen.MainScreen.Bounds.Height); public override void ViewDidLoad () { UIGraphics.BeginImageContext(new SizeF(PDFRectangle.Width, PDFRectangle.Height)); CGContext context = UIGraphics.GetCurrentContext(); context.SaveState(); CGPDFDocument pdfDoc = CGPDFDocument.FromFile("test.pdf"); CGPDFPage pdfPage = pdfDoc.GetPage(1); context.DrawPDFPage(pdfPage); UIImage testImage = UIGraphics.GetImageFromCurrentImageContext(); pdfDoc.Dispose(); context.RestoreState(); UIImageView imageView = new UIImageView(testImage); UIGraphics.EndImageContext(); View.AddSubview(imageView); } A section of the CGPDFPage is displayed but rotated back-to-front and upside down. My question is, how do I select the full pdf page and flip it round to display correctly. I have seen a few examples using ScaleCTM and TranslateCTM but couldn't seem to get them working. Any examples in ObjectiveC are fine, I'll take all the help I can get :) Thanks

  • How to check at runtime if a class implements certain interface?

    - by mare
    Let's say I have some content classes like Page, TabGroup, Tab, etc. Certain of those will be implementing my IWidgetContainer interface - it means they will geet an additional field named ContainedItems from the interface and some methods for manipulating this field. Now I need to reflect the fact that some class implements this interface by rendering out some special custom controls in my ASP.NET MVC Views (like jQuery Add/Remove/Move/Reorder buttons). For instance, TabGroup will implement IWidgetContainer because it will contain tabs but a tab will not implement it because it won't have the ability to contain anything. So I have to somehow check in my view, when I render my content objects (The problem is, I use my base class as strong type in my view not concrete classes), whether it implements IWidgetContainer. How is that possible or have I completely missed something? To rephrase the question, how do you reflect some special properties of a class (like interface implementation) in the UI in general (not necessarily ASP.NET MVC)? Here's my code so far: [DataContract] public class ContentClass { [DataMember] public string Slug; [DataMember] public string Title; [DataMember] protected ContentType Type; } [DataContract] public class Group : ContentClass, IWidgetContainer { public Group() { Type = ContentType.TabGroup; } public ContentList ContainedItems { get; set; } public void AddContent(ContentListItem toAdd) { throw new NotImplementedException(); } public void RemoveContent(ContentListItem toRemove) { throw new NotImplementedException(); } } [DataContract] public class GroupElement : ContentClass { public GroupElement() { Type = ContentType.Tab; } } Interface: interface IWidgetContainer { [DataMember] ContentList ContainedItems { get; set; } void AddContent(ContentListItem toAdd); void RemoveContent(ContentListItem toRemove); }

  • Why are controls (null) in awakeFromNib?

    - by fuzzygoat
    This is a follow on from another question regarding why I could not set UIControls in awakeFromNib. The answer to that is that as you can see below the controls are nil in the awakeFromNib, although they are initialised to the correct objects by the time we get to viewDidLoad. I setup the view the same as I always do, should I be doing something different to access them here, the xib(nib) was designed and saved with the current version of Image Builder. CODE: @interface iPhone_TEST_AwakeFromNibViewController : UIViewController { UILabel *myLabel; UIImageView *myView; } @property(nonatomic, retain)IBOutlet UILabel *myLabel; @property(nonatomic, retain)IBOutlet UIImageView *myView; @end . @synthesize myLabel; @synthesize myView; -(void)awakeFromNib { NSLog(@"awakeFromNib ..."); NSLog(@"myLabel: %@", [myLabel class]); NSLog(@"myView : %@", [myView class]); //[myLabel setText:@"AWAKE"]; [super awakeFromNib]; } -(void)viewDidLoad { NSLog(@"viewDidLoad ..."); NSLog(@"myLabel: %@", [myLabel class]); NSLog(@"myView : %@", [myView class]); //[myLabel setText:@"VIEW"]; [super viewDidLoad]; } OUTPUT: awakeFromNib ... myLabel: (null) myView : (null) viewDidLoad ... myLabel: UILabel myLabel: UIImageView Much appreciated ... gary

  • Converting rows to Columns in SQL

    - by Ram
    I have a table (actually a view, but simplified my example to a table) which gives me some data like this id CompanyName website 1 Google google.com 2 Google google.net 3 Google google.org 4 Google google.in 5 Google google.de 6 Microsoft Microsoft.com 7 Microsoft live.com 8 Microsoft bing.com 9 Microsoft hotmail.com I am looking to convert it to get a result like this CompanyName website1 website2 website3 website 4 website5 website6 ----------- ------------- ---------- ---------- ----------- --------- -------- Google google.com google.net google.org google.in google.de NULL Microsoft Microsoft.com live.com bing.com hotmail.com NULL NULL I have looked into pivot but looks like the record(row values) cannot be dynamic (i.e can only be certain predefined values). Also, if there are more than 6 websites, I want to limit it to the first 6 Dynamic pivot makes sense, but I would have to incorporate it into my view ?? Is there a simpler solution for this ? Here are the SQL scripts CREATE TABLE [dbo].[Company]( [id] [int] NULL, [CompanyName] [varchar](50) NULL, [website] [varchar](50) NULL ) ON [PRIMARY] GO insert into company values (1,'Google','google.com') insert into company values (2,'Google','google.net') insert into company values (3,'Google','google.org') insert into company values (4,'Google','google.in') insert into company values (5,'Google','google.de') insert into company values (6,'Microsoft','Microsoft.com') insert into company values (7,'Microsoft','live.com') insert into company values (8,'Microsoft','bing.com') insert into company values (9,'Microsoft','hotmail.com')

  • Why doesn't my UIViewController class keep track of an NSArray instance variable.

    - by TaoStoner
    Hey, I am new to Objective-C 2.0 and Xcode, so forgive me if I am missing something elementary here. Anyways, I am trying to make my own UIViewController class called GameView to display a new view. To work the game I need to keep track of an NSArray that I want to load from a plist file. I have made a method 'loadGame' which I want to load the correct NSArray into an instance variable. However it appears that after the method executes the instance variable loses track of the array. Its easier if I just show you the code.... @interface GameView : UIViewController { IBOutlet UIView *view IBOutlet UILabel *label; NSArray *currentGame; } -(IBOutlet)next; -(void)loadDefault; ... @implementation GameView - (IBOutlet)next{ int numElements = [currentGame count]; int r = rand() % numElements; NSString *myString = [currentGame objectAtIndex:(NSUInteger)r]; [label setText: myString]; } - (void)loadDefault { NSDictionary *games; NSString *path = [[NSBundle mainBundle] bundlePath]; NSString *finalPath = [path stringByAppendingPathComponent:@"Games.plist"]; games = [NSDictionary dictionaryWithContentsOfFile:finalPath]; currentGame = [games objectForKey:@"Default"]; } when loadDefault gets called, everything runs perfectly, but when I try to use the currentGame NSArray later in the method call to next, currentGame appears to be nil. I am also aware of the memory management issues with this code. Any help would be appreciated with this problem.

  • Want to mimic iphone address book search (In terms of interface & interaction)

    - by mr-sk
    Hi, When you do a search in the address book the flow is: 1) Select the search bar 2) The right most transparent a-z index is removed 3) A transparent black window is placed over the current UITableView 4) When you begin typing, a new UITableView is loaded with no data 5) The UITableView is populated with data as you type. 6) If you select an item you are brought to it 7) If you cancel the search you return to the main UITalbeView My first real question is, how do I load a new UITableView when a user begins searching? Is it as easy as popping a new view on the stack? It would then be a seperate .m/.h file with its own implementation? The second question is how do you remove the right most index? Or just that just go away when you render the new (blank) UITableView? I've gotten search working, but mine does it in the same UITableView, which when you start contains like 2K results, is grouped (A results under A Heading, etc) and has a right most index. I'd be happy leaving the results in the table, if I could; 1) Remove the rightmost a-z index 2) Drop the table groupings 3) Tell the view I only have N search results so it will build the scroll bar correctly. Thanks for your input; sk
