  • Looking for a filtered dropdown list for ASP.NET.

    - by ProfK
    I have some DropDownList controls where the list is very large, so I would like to have a means for the user to filter the list, either based on other fields, e.g. region, or on the first letters typed in a textbox. How can I achieve this in ASP.NET? Is the an open source control out there that will help me?

  • IE7 and IE8: Float clearing without adding empty elements

    - by tk-421
    Hello, I'm having a problem similar to the one described here (without a resolution): http://stackoverflow.com/questions/2467745/ie7-float-and-clear-on-the-same-element The following HTML renders as intended in Firefox but not in (both) IE7 and IE8: <html> <head> <style> ul { list-style-type: none; } li { clear: both; padding: 5px; } .left { clear: left; float: left; } .middle { clear: none; float: left; } .right { clear: right; float: left; } </style> </head> <body> <ul> <li>1</li> <li class="left">2</li> <li class="right">3</li> <li class="left">4</li> <li class="middle">5</li> <li class="right">6</li> <li>7</li> </ul> </body> </html> This is a form layout, and in Firefox the results appear like: 1 2 3 4 5 6 7 That's what I'm going for. In IE7 and IE8 however, the results are: 1 2 3 5 6 4 7 [Note: I don't want to float anything to the right because I want the fields on my form to left-align correctly, without a giant space in-between the floated fields to account for the parent container's width.] Apparently I need a full clear, and can probably add an empty list-item element to the list to force clearing, but that seems like a dumb solution and sort of defeats the purpose. Any ideas? I've spent a few hours reading and trying different options without success.

    I have a Django form that is working fine. I'd like to save the data it submits to a CSV file. Is there a "best practice" way to do this? I need to include blank fields in the CSV file where the user has not filled in a "required=False" field

  • Issue with Usercontrol and Border Style

    - by Ram
    Hi, I have created a user control ( custom data grid view control). I have used the code specified at MSDN [site][1] [1]: http://support.microsoft.com/kb/316574 to set the border style . I am able to see the selected border style in designer. Like None, FixedSingle or Fixed3D. But when I set the border style to FixedSingle, the border does not appear at runtime. Do I need to draw it manually in the OnPaint method?

  • database design: table with large amount of columns (50+) or many sub tables with small amount of co

    - by Guillaume
    In our oroject we already have a lots of tables (100+). Some of them contains a lot of columns (50-100) and we are facing the need of adding more columns from time to time. What do you think is best - from maintenance and performance point of view - to split these huge tables in smaller entities or to keep the tables the way they are ? We are using an ORM tools, so we don't need to write custom request.

  • Challenging yourself as a programmer?

    - by Kevin
    We used to be a Coldfusion development shop before hopping over to PHP in 2008, now we primarily develop custom Drupal websites. I enjoyed going from CF to PHP, but I feel like I am getting a bit stale. I have been looking at different things like Ruby, Python, Obj C (iPhone). The problem is, there just isn't enough time in the day. What would be a fun new thing to learn that would refresh me a bit and challenge myself to learn more?

  • mysql join on two indexes takes long time!!

    - by Alaa
    Hi All I have a custom query in dripal, this query is: select count(distinct B.src) from node A, url_alias B where concat('node/',A.nid)= B.src; now, nid in node is primary key and i have made src as an index in url_alias table. after waiting for more than a minute i got this: +-----------------------+ | count(distinct B.src) | +-----------------------+ | 325715 | +-----------------------+ 1 row in set (1 min 24.37 sec) now my question is: why did this query take this long, and how to optimize it?? Thanks for your help

  • Is this a problem typically solved with IOC?

    - by Dirk
    My current application allows users to define custom web forms through a set of admin screens. it's essentially an EAV type application. As such, I can't hard code HTML or ASP.NET markup to render a given page. Instead, the UI requests an instance of a Form object from the service layer, which in turn constructs one using a several RDMBS tables. Form contains the kind of classes you would expect to see in such a context: Form= IEnumerable<FormSections>=IEnumerable<FormFields> Here's what the service layer looks like: public class MyFormService: IFormService{ public Form OpenForm(int formId){ //construct and return a concrete implementation of Form } } Everything works splendidly (for a while). The UI is none the wiser about what sections/fields exist in a given form: It happily renders the Form object it receives into a functional ASP.NET page. A few weeks later, I get a new requirement from the business: When viewing a non-editable (i.e. read-only) versions of a form, certain field values should be merged together and other contrived/calculated fields should are added. No problem I say. Simply amend my service class so that its methods are more explicit: public class MyFormService: IFormService{ public Form OpenFormForEditing(int formId){ //construct and return a concrete implementation of Form } public Form OpenFormForViewing(int formId){ //construct and a concrete implementation of Form //apply additional transformations to the form } } Again everything works great and balance has been restored to the force. The UI continues to be agnostic as to what is in the Form, and our separation of concerns is achieved. Only a few short weeks later, however, the business puts out a new requirement: in certain scenarios, we should apply only some of the form transformations I referenced above. At this point, it feels like the "explicit method" approach has reached a dead end, unless I want to end up with an explosion of methods (OpenFormViewingScenario1, OpenFormViewingScenario2, etc). Instead, I introduce another level of indirection: public interface IFormViewCreator{ void CreateView(Form form); } public class MyFormService: IFormService{ public Form OpenFormForEditing(int formId){ //construct and return a concrete implementation of Form } public Form OpenFormForViewing(int formId, IFormViewCreator formViewCreator){ //construct a concrete implementation of Form //apply transformations to the dynamic field list return formViewCreator.CreateView(form); } } On the surface, this seems like acceptable approach and yet there is a certain smell. Namely, the UI, which had been living in ignorant bliss about the implementation details of OpenFormForViewing, must possess knowledge of and create an instance of IFormViewCreator. My questions are twofold: Is there a better way to achieve the composability I'm after? (perhaps by using an IoC container or a home rolled factory to create the concrete IFormViewCreator)? Did I fundamentally screw up the abstraction here?

  • How to set an image based on iphone platform in objective-c

    - by Toran Billups
    I'm moving my application from 3.x to 4.x as I prepare for the app store and found that I need to have 2 copies of all my custom pngs - my question is how can I determine what img to show and when. Example - how do I know to show the Find.png vs the [email protected] Is it "safe" or "correct" to look for 4.x specific apis or does the iphone have a way to determine what platform you are on at runtime? Thank you in advance

  • Rails HTML editor to create forms

    - by Ignace
    Hey all, I'm looking for a HTML editor which can be (easiliy) integrated in a RoR app that has the possibility to create forms. Not forms per se, but I need the possibility to add radiobuttons, input fields, checkboxes and so on. I loved the smoothness of TinyMCE, but apparently this doesn't take me far enough. Does there exists such a gem/plugin? Thanks!

  • Visual Studio Colour Settings

    - by Ian
    I've got a custom colour set in Visual Studio and one of the colours when debugging is making things a bit of a misery. Unfortunately I can't figure out which one it is, and when going through and changing all the light background ones, it still remains. Can anyone point me in the right direction? In this screenshot the current line is yellow, and the caller is the white/cream sort of colour which is the one I want to change... Thanks very much! :)

  • how to have two controller actions, one shared view for Zend_Controller_Action Class?

    - by arendn
    Hi Guys, How do you specify a custom view script for a given Controller Action method? For example: Class UserGalleryController extends Zend_Controller_Action { public function fooAction() { $this->view->actionMsg = 'foo'; // (uses foo.phtml automagically) } public function barAction() { $this->view->actionMsg = 'bar'; //use foo's view script ????? } } I basically want to have one view script (foo.phtml) Thanks :-)

  • How to switch from VARCHAR to TEXT in SQL 2000?

    - by MatthewMartin
    What do I need to consider before I switch a bunch of fields from VARCHAR(bignumber) to TEXT? Aside from performance, and sometime in the far future TEXT will be deprecated, and aside from the fact that it looks like I need to drop and recreate the table to alter the column's data type? This is for SQL 2000-- I can't do VARCHAR(max) and VARCHAR(8000) isn't large enough.

  • Open source equivelants to VS / web reference proxy classes?

    - by seraphym
    As an ASP.NET developer, I'm used to working with how VS/C# transparently autogens proxy classes for web references (yes, I know, we're spoiled), but now that I'm creating documentation for more than one coding platform I'm trying to discover what the equivelant to that is in any other framework. So is there a similar way to work transparently with web reference proxy classes for say, RoR, PHP, and Python? And if there's nothing integrated, are there tools you recommend to autogen the proxy classes, or do you recommend to roll custom classes?
