Hi all, and thanks in advance for your great job.

I a MultiColumnComboBox with multiple selection i need to show a string that display how many items are currenctly selected, instead of the list of SearchAutoCompleteBoxItem. But i can't figure out how to do this without working on the source code.

Anyone can help me, please? Thank you very much.

I am reviving an application that must remain in Visual Studio 2010 and uses .NET 4.0.
My projects all use Telerik's Binaries.NoXaml.

I am renewing my license to use the latest Telerik release.
While those wheels are in motion, I downloaded the latest trial and find there is no WPF40 folder in Binaries.NoXaml.
I tried referencing the WPF45 dlls, but I'm getting build errors such as:
The type reference cannot find a public type named 'RadButton'

I'm not sure if this is because I'm referencing the WPF45 dlls or something else.
I do see there is a WPF40 folder in the regular Binaries folder.
This makes me question if the WPF40 Binaries.NoXaml are missing.

Are they missing?
Or should WPF45 work fine?
I look forward to any advice.

I'm using MVVM to data bind the items of a RadTreeListView to an observable collection.

When the value of the DataMemberBinding is updated in the View-Model, the value is correctly reflected in the RadTreeListView GridViewCell.   But, cells where the value was updated are highlighted, as shown in the attached screenshot.   I would prefer the updated cells not be highlighted.

Hi,

My UI for WPF (2018 R1) used to work very well, but some days ago the design-time components stopped working. All the Rad controls lost their styles in the designer; however in run time they work just fine.

When Visual Studio (2017, v15.8.4) launches, it shows the following messages in the General output channel:

I tried every method I can find on the web with a related topic, including but not limited to deleting obj and bin folders, cleaning and rebuilding, reinstalling Telerik UI for WPF and Visual Studio etc. etc..

I tracked these exceptions down with Fusion Log Viewer, and it seems they are trying to load assemblies named Telerik.Windows.Data and Telerik.Windows.Core.Design, which unfortunately are not found by Visual Studio (however they do exist in the installation and the lib folder under my solution).

I tried to copy all the telerik.*.dll files to C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\common7\ide\ in order to let Visual Studio to find them, this successfully eliminated the error messages in the General output channel, however all the Rad controls now become invisible in the designer.

I think this issue started when I changed all the projects in my solution to target x64 CPU instead of Any CPU, but I'm not sure because the problem still exists when I switch them back to Any CPU.

Hi i'm using RadSpreadSheet inside a ControlTemplate and binding the control with Workbook property.

But it's not getting affected, whenever my binding is changed it does not get refreshed inside the control and the UI is not rendered.

And if i manually change the binding property at run time in xaml, then the control gets the binded and renders the data it on UI.

I have attached the code of the control in which i'm using the RadSpreadSheet.
