  • How do I know if a drag/drop has been cancelled in WPF

    - by Jon Mitchell
    I'm writing a user control in WPF which is based on a ListBox. One of the main pieces of functionality is the ability to reorder the list by dragging the items around. When a user drags an item I change the items Opacity to 50% and physically move the item in an ObservableCollection in my ViewModel depending on where the user wants it. On the drop event I change the Opacity back to 100%. The problem I've got is that if the user drags the item off my control and drops it somewhere else then I need to change the Opacity back to 100% and move the item back to where it was when the user started the drag. Is there an event I can handle to capture this action? If not is there any other cunning way to solve this problem?

  • better for-loop syntax for detecting empty sequences?

    - by Dmitry Beransky
    Hi, Is there a better way to write the following: row_counter = 0 for item in iterable_sequence: # do stuff with the item counter += 1 if not row_counter: # handle the empty-sequence-case Please keep in mind that I can't use len(iterable_sequence) because 1) not all sequences have known lengths; 2) in some cases calling len() may trigger loading of the sequence's items into memory (as the case would be with sql query results). The reason I ask is that I'm simply curious if there is a way to make above more concise and idiomatic. What I'm looking for is along the lines of: for item in sequence: #process item *else*: #handle the empty sequence case (assuming "else" here worked only on empty sequences, which I know it doesn't)

    - by Michal Dymel
    Hi, I have a layout defined in XML. It contains also: <RelativeLayout android:id="@+id/item" android:layout_width="fill_parent" android:layout_height="wrap_content" /> I would like to inflate this RelativeView with other XML layout file. I may use different layouts depending on a situation. How should I do it? I was trying different variations of RelativeLayout item = (RelativeLayout) findViewById(R.id.item); item.inflate(...) But none of them worked fine. Heeelp ;)

  • DispatcherOperations.Wait()

    - by Mark
    What happens if you call dispatcherOperation.Wait() on an operation that has already completed? Also, the docs say that it returns a DispatcherOperationStatus, but wouldn't that always be Completed since it (supposedly) doesn't return until it's done? I was trying to use it like this: private void Update() { while (ops.Count > 0) ops.Dequeue().Wait(); } public void Add(T item) { lock (sync) { if (dispatcher.CheckAccess()) { list.Add(item); OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Add, item)); } else { ops.Enqueue(dispatcher.BeginInvoke(new Action<T>(Add), item)); } } } I'm using this in WPF, so all the Add operations have to occur on the UI thread, but I figured I could basically just queue them up without having to wait for it to switch threads, and then just call Update() before any read operations to ensure that the list is up to date, but my program started hanging.

Any idea how to do this besides implementing my own IList? Thanks in advance, Frank

  • kQuery : Trying to find a specific instance of a class by number

    - by mattelliottIT
    I guess I have just hit a mental block with this one; maybe some fresh eyes will help. Basically I have a few instance of the class "menu-item" which when clicked call the click function via jQuery and bring up a video. Instead of giving each on an id as well as a class I am trying to find which instance of the class was clicked (1, 2, 3, etc). Just can't seem to get it though. //click listener for menu-items $('.menu-item').click(function(event) { var o = $('.menu-item'); var count = o.length(); // switch(count) { case 0 : filename == 'letters'; break; case 1 : filename == 'the-gift'; break; } var videoPlayer = '<video controls width="618px">'; videoPlayer += '<source src="_video/' + filename + '.mp4" />'; videoPlayer += '</video>'; //place video $('#videoCont').html(videoPlayer); }); I'm trying to create an array there where each instance of the 'menu-item' is one array item. (btw, for now I am just proofing this with an mp4 filetype before I add in the ogv and webm formats). Thanks for any and all help!

  • Adding a first and last class to Wordpress' widget contents

    - by user571188
    In Wordpress, I'm looking for some way to add a "last" and a "first" class to list items inside Wordpress widgets. The HTML could look like this: <div class="widget-area"> <ul > <li class="widget_recent_comments"> <h3 class="widget-title">Recent comments</h3> <ul id="recentcomments"> <li class="recentcomments">Comment 1</li> <li class="recentcomments">Comment 2</li> <li class="recentcomments">Comment 3</li> <li class="recentcomments">Comment 4</li> </ul> </li> <li class="widget_my_links"> <h3 class="widget-title">My links</h3> <ul id="my-links"> <li class="item">Link 1</li> <li class="item">Link 2</li> <li class="item">Link 3</li> <li class="item">Link 4</li> <li class="item">Link 5</li> </ul> </li> </ul></div> In this example above i'd like to have first/last classes added to the li with "Comment 1", "Comment 4", "Link 1" and "Link 5". Is there an easy workaround for this? (I don't want to do this with javascript) Thank you.

  • can the point have a longer history

    - by stevejb
    Hello, I often find myself in the following situation. Say I was editing a file with this contents \begin{itemize} \item \end{itemize} I really like http://stackoverflow.com ! And say the point was after the word \item. What I want to do is select http://stackoverflow.com , C-w it, and go back to \item, and yank it there. What I would do is C-s htt and that would bring the point to the 2nd t of http, and from there I would go backwards, C-SPC on h, then select the rest of the word. Now, I would like to use something like C-x C-x to bring me back to \item, but it will instead bring me back to the h of http. Is there a command like C-x C-x which brings the point back through its history of location? Thanks,

  • Deleting list items via ProcessBatchData()

    - by q-tuyen
    You can build a batch string to delete all of the items from a SharePoint list like this: 1: //create new StringBuilder 2: StringBuilder batchString= new StringBuilder(); 3: 4: //add the main text to the stringbuilder 5: batchString.Append(""); 6: 7: //add each item to the batch string and give it a command Delete 8: foreach (SPListItem item in itemCollection) 9: { 10: //create a new method section 11: batchString.Append(""); 12: //insert the listid to know where to delete from 13: batchString.Append("" + Convert.ToString(item.ParentList.ID) + ""); 14: //the item to delete 15: batchString.Append("" + Convert.ToString(item.ID) + ""); 16: //set the action you would like to preform 17: batchString.Append("Delete"); 18: //close the method section 19: batchString.Append(""); 20: } 21: 22: //close the batch section 23: batchString.Append(""); 24: 25: //preform the batch 26: SPContext.Current.Web.ProcessBatchData(batchString.ToString()); The only disadvantage that I can think of right know is that all the items you delete will be put in the recycle bin. How can I prevent that? I also found the solution like below: // web is a the SPWeb object your lists belong to // Before starting your deletion web.Site.WebApplication.RecycleBinEnabled = false; // When your are finished re-enable it web.Site.WebApplication.RecycleBinEnabled = true; Ref [Here](http://www.entwicklungsgedanken.de/2008/04/02/how-to-speed-up-the-deletion-of-large-amounts-of-list-items-within-sharepoint/) But the disadvantage of that solution is that only future deletion will not be sent to the Recycle Bins but it will delete all existing items as well which user do not want. Any idea to prevent not to delete existing items? Many thanks in advance, TQT

  • Getting the value from an array in the model in rails

    - by slythic
    Hi all, I have a relatively simple problem. I have a model named Item which I've added a status field. The status field will only have two options (Lost or Found). So I created the following array in my Item model: STATUS = [ [1, "Lost"], [2, "Found"]] In my form view I added the following code which works great: <%= collection_select :item, :status, Item::STATUS, :first, :last, {:include_blank => 'Select status'} %> This stores the numeric id (1 or 2) of the status in the database. However, in my show view I can't figure out how to convert from the numeric id (again, 1 or 2) to the text equivalent of Lost or Found. Any ideas on how to get this to work? Is there a better way to go about this? Many thanks, Tony

  • List in a Python class shares the same object over 2 different instances?

    - by zfranciscus
    I created a class: class A: aList = [] now I have function that instantiate this class and add items into the aList. note: there are 2 items for item in items: a = A(); a.aList.append(item); I find that the first A and the second A object has the same number of items in their aList. I would expect that the first A object will have the first item in its list and the second A object will have the second item in its aList. Can anyone explain how this happens ? PS: I manage to solve this problem by moving the aList inside a constructor : def __init__(self): self.aList = []; but I am still curious about this behavior

  • ASP.NET MVC 3 NOT showing appropriate view, action called using jquery

    - by TunAntun
    I have a small problem. My action is : public ViewResult SearchForRooms(int HotelDDL) { List<Room> roomsInHotel = bl.ReturnRoomsPerHotel(HotelDDL); return View(roomsInHotel); } Here is the jquery that is calling the action: <script type="text/javascript" language="javascript"> $(document).ready(function () { $("#HotelDDL").change(function () { var text = $("#HotelDDL option:selected").text(); var value = $("#HotelDDL option:selected").val(); alert("Selected text=" + text + " Selected value= " + value); $.post("/Home/SearchForRooms", { HotelDDL: $("#HotelDDL option:selected").val() }); }); }); </script> And finally, here is the View that should be called: @model IEnumerable<RoomReservation.Entities.Entities.Room> @{ ViewBag.Title = "Search"; } <h2>Result</h2> <table> <tr> <th> City </th> <th> Hotel </th> <th> Room label </th> <th> Number of beds </th> <th> Price per night </th> <th></th> </tr> @foreach (var item in Model) { <tr> <td> @Html.DisplayFor(modelitem=>item.Hotel.City.Name) </td> <td> @Html.DisplayFor(modelItem => item.Hotel.Name) </td> <td> @Html.DisplayFor(modelItem => item.Name) </td> <td> @Html.DisplayFor(modelItem => item.NumberOfBeds) </td> <td> @Html.DisplayFor(modelItem => item.PricePerNight) </td> </tr> } </table> Everthing is working ok (databse return all rooms correctly) except final view rendering. I have tried Phil's tool but it doesn't give me any suspicious hints: RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes); So, why is it not showing after jscript send it's post method to SearchForRooms()? Thank you P.S. If you need any other piece of code please just say so.

  • Iterating ListView items in Android

    - by pocoa
    I want to iterate a list of items into a ListView. This code below is not enough to iterate all the items into the list because of the weird behaviour of getChildCount() function which only returns the visible item count. for (int i = 0; i < list.getChildCount(); i++) { item = (View)list.getChildAt(i); product = (Product)item.getTag(); // make some visual changes if product.id == someProductId } My screen displays 7 results and when there are more than 7 items into the list, it's not possible to access to the 8th item or so.. Only visible items.. Should I use ListIterator instead? Thanks.

  • WPF WrapPanel - all items should have the same width

    - by John
    I have a ListBox whose ItemsPanel I have replaces with a WrapPanel. The WrapPanel now hosts the databound ListboxItems. Each item has a variable sized text in it, giving each item a different width. However, I want the width to be constant so that all items have the same width as the item with the longest text. Is that possible?

  • sifr menu list problems, height of object calculated wrong

    - by armyofda12mnkeys
    I am using Drupal and have sifr set on list items, and also a, a:hover are set via Drupal so that the links hover. I looked at the sifr3-rules.js file drupal's render module creates and it looks good. and in fact my other sifr items look fine... But the list item ones are goofing for some reason... There is extra space below the list, so if i have a list item, and inside of that, I have a unordered list with more list items, the Flash Object made in the 1st li (which will cover the rest of the sublist items too), is too bid so you see space under the children until the next parent li comes up. (so looks like extra bottom padding on that portion of the list in IE8... in FF almost similar but each subitem has space at bottom... with javascript turned off, you see the list items look fine by themselves).... Also if the parent list item is shorter than the sub list items text, the width for the flash object is set only as long as the first list item, and therefore cuts off the rest the sublist item's text. Any idea how to resolve any of these? Only unusual thing i see i am doing is setting forceSingleLine and preventWrap (which dont make a difference if taken off). ****Edit, I may just try to figure out how to get Drupal's menu-block module to output a around my hyperlinks in the list items... then i can target the div's with my rule (and the a,a:hover rules will apply), so each menu item gets its own sifr object instead of sifr3 trying to figure out how to do the lists and sublists. Very useful to me is anyone knows a way to target a hyperlink (<a> tag) and also allow a:hover rules. I know how to do it with pretend another tag that includes hyperlinks, like if i had <h2><a>sometitle</a></h2>, i could have a rule for h2, but then use the a, a:hover rules in the sifr3-rules.js file to target that. so i would need a way to target the hyperlink in the list, but also apply a :hover to it (not sure if this can be done since its not underneith for example the h2 tag).
