Thank you for contacting us.
Having reviewed the provided details, I suppose that the described behavior is due to the fact that after the upgrade has been performed the UI for Silverlight
's distribution was successfully updated but the version of the Telerik controls which is registered into the Visual Studio Toolbox is still the older one. What I advice is to use our Toolbox Configurator
, which will help you to update it. Please take a look at the following steps, which could be of help in achieving this:
1. Launch Visual Studio and open your project
2. Open Toolbox explorer and right-click on it
3. Select Reset Toolbox
option, as it is shown at the attached reset-toolbox.png
4. Having reset the Visual Studio Toolbox, select Launch Toolbox Configurator
item under the Telerik
-> UI for Silverlight
5. Select the desired version and press Finish
6. Restart Visual Studio
Could you please perform the steps above and let us know in case the issue still persists?
Should you have additional questions or need further assistance, do not hesitate to contact us again.
