I am trying to use the new DragAndDrop manager with the RadComboBox, I want to be able to drop an element from a treeview onto the ComboBox and apply a custom Drop Event that will select the dragged entity from the list. I have AllowDrop="True" on the ComboBox and I know the Treeview is set up correctly because I use it to drag to a ListBox. When the line DragDropManager.AddDropHandler(RadComboBoxBelongsTo, OnDrop); is run I get the error: Cannot find a Resource with the Name/Key DraggableItem. How do I drag to a RadComboBox??

Sorry, should have posted this on the Silverlight Forum, not sure if its the same for WPF.

I created a simple project to address our problem with RadControls (Docking, RichTextBox and TreeView), could you provide me a support ticket so I can upload the zip file.  Thanks.

I have two entities, for instance entityA and entityB inherited from entityB. In ObjectContext there is
ObjectSet<entityA> entityAs;
But I need an ObjectResult<entityB>, and has created this (custom) property on ObjectContext:
ObjectResult<entityB> entityBs
{ ... }
So when I user entityBs as QueryName in RadEntityFrameWorkDataSource (in XAML), then nearly all works fine except AddNew, because the QueryName is used for getting ObjectResult<> property value of ObjectContext, and for entitySetName.
Can I somehow enforce the real base entit class's set name for use as entitySetName, and (any) ObjectQuery as object query used to create QueryabelEntityCollection?

It is not a solution, when I use for QueryName the base ObjectSet's name (and approperiate FilterDescription), because the AddNew produce a base class instance not a derived class's one. 

(ok, I can create manually QueryabelEntityCollection<entityB>, but it is not real beuty solution :))

I would like to disable Keyboard focus for the RichTextBox.
My RichTextBox is acting more like a viewer, with possibility to select text but not edit.
When I use snoop to check te keyboard focus on my application, I see Keyboard.FocusedElement = Caret
I'm experiencing difficulties disabling this focus.

When I execute UIElement.MoveFocus(new TraversalRequest(FocusNavigationDirection.Up)) I can't either move the focus

Hello,

I've got a Problem with the New Q1 2012 WPF RadTileView.
If i user the TileStateChanged Event (Online Doc), and set the FluidControl State Manualy to Large,Small, Normal, the layout looks Broken (File q12012.png , Version: 2012.1.215.40).
If i run exactly the same Code with the old Assemblys (2010.3.1110.40), the Layout looks correct.

The Animation of the TileItem are also Smoother in the Older Release as in the new one.

Is there any Workaround, for solving this Problem, or is it simply a Bug?

Greetings

Hi,

I'm creating a chart that is based off the MeteoChart example. Specifically, I'm using the same concepts as the SplineLabelStyle in the MeteoChart to display custom icons overriding the default item label.

The MeteoChart has the following XAML to style the SeriesItemLabel with a custom control template that contains custom icons:

What I'd like to do is add a tooltip to this image to display more information, ie:

The problem is that the above XAML doesn't work. While the example runs, tooltips are not displayed when hovering over the icon. I've tried shifting the tooltip to the canvas instead and even tried displaying fixed text as the tooltip, however none of these alternatives get tooltips to display.

I would like to display the tooltip on the customized item label because:

1. these labels are easier targets to hover over instead of point marks,
2. the labels are displayed in a different location to the point mark, and finally
3. I'm actually hiding the point mark in my actual scenario (I'm just displaying the icons).

How can I define tooltips for custom item labels?

Alternatively, how can I customize the PointMarkItemStyle to display custom icons (and then I can use the default item tooltip provided).

Kind regards,
Dave.

I am doing a search/replace in code using the RadDocument and I am getting a strange null error.

Here is the code:

doc.Selection.Clear();

            DocumentTextSearch search = new DocumentTextSearch(doc);

            var rangesTrackingDocumentChanges = new List<TextRange>();

            var resultRanges = search.FindAll(searchText);

 

            foreach (var textRange in resultRanges)

            {

                TextRange newRange = new TextRange(new DocumentPosition(textRange.StartPosition, true), new DocumentPosition(textRange.EndPosition, true));

                rangesTrackingDocumentChanges.Add(newRange);

            }

 

            foreach (var textRange in rangesTrackingDocumentChanges)

            {

                doc.CaretPosition.MoveToPosition(textRange.StartPosition);

                doc.DeleteRange(textRange.StartPosition, textRange.EndPosition);

                doc.Insert(mergeText, new Telerik.Windows.Documents.Model.Styles.StyleDefinition());

                textRange.StartPosition.Dispose();

                textRange.EndPosition.Dispose();

            }

When the RadDocument is simple,this works fine, however, when I put the Merge fields in Tables, it is throwing an error on the search.FindAll() method:

System.NullReferenceException: Object reference not set to an instance of an object.
