Currently I have installed a copy of Teleriks UI for WPF, UI for AJAX.NET, UI for Silverlight, and UI ASP.NET.MVC, and have obtained a running application from a tortoiseSVN project, however, when I go to the designer I get the following error:

'RadComboBox' TargetType does not match type of element 'NumberComboBox'.

Any thoughts on how to remedy it.  Kind regards, 

Martin

I have a RadDiagramTextShape without connectors.  I don't want to connect to text shapes.

So I clear then using this line of code:

    ((RadDiagramTextShape)Shape).Connectors.Clear();

My problem is when a user changes to the Connector Tool ( diagram.ActiveTool = MouseTool.ConnectorTool) and clicks within the RadDiagramTextShape  an unhandled exception is thrown:

An unhandled exception of type 'System.InvalidOperationException' occurred in Telerik.Windows.Controls.Diagrams.dllAdditional information: The shape has no connectors defined.

Is there a way to prevent this? 

I'm trying to solve the following issue:

I load a cartographic image, jpg of size 9472x6656 px and it covers a geographical rectangle area of the following lat&long: 42, 12.3   41.17, 13.88 (decimal degrees)

I'm loading using directly XAML with the following code:




I'm trying to understand how coordinates and image size are releated.
It seems that the coordinates I set for the image provider (GeoBounds) are not right, and image is positioned somewhere else.

Which is the right way to position an image using UriImageProvider? There is no documentation online on that.
I've tried to following the suggestion in other post (http://www.telerik.com/forums/uriimageprovider-questions)
setting bounds with the following code, but I get only an error:


as the view.ZoomLevel property get an impossible number, something like: 243578438.

how can i change the OpenCloseButtonStyle title, say from view galleries to somthing of my own?

Normally filtering is done for event like LostFocus, pressing the enter button or selection change. How can I supress that behavior and trigger filtering later (also how?).

We are having a problem grouping objects in the RadGridView.
For example ,one of the properties of our objects is named:Changed.
When the application is loaded,the RadGridView and GridViewScrollbar behave well.
After grouping ,if the value of the property(Changed) changes in a specific object,then it should move to the appropriate group.
Unfortuntely,this does not happen.
To solve this bug ,we tried to manually sort oir regroup.
This solved the current bug,but created another bug.
The GridViewScrollbar of the grid moves up suddenly and does not stay in its original position.
The vertical offset =0.
In addition , when we return to the initial state (cancel the grouping ),the GridViewScrollbar still changes its position.
The objects in the items source update all the time.
In addition , we raise a property changed event on the collection bound to the item source.

How is this accomplished?

thanks in advance for your help.

Hi

we have a RadSlider with IsSelectionRangeEnabled=True, our requirement is that both Thumbs should push one another while dragging.

I would like that you confirm to me whether this is possible with the current RadSlider control. It seems that setting IsCoercionSuppressed to true or false does not yield our desired effect.

I am looking at using the Telerik WPF 2014.1's Office 2013 implicit theme. How can I allow mixed-casing in the Header Captions instead of always having upper-cased text?

Kind Regards,
Albert
