hi! Dimitirna~

1. my telerik version is 2014 q3

2. Touch is not need to my project

    and I don't know how to disable touch.

    let me know the way to disable touch.

3. There is some problems in making demo.

    But project condition is simple.

    1. Create UserControl

    2. That control has a RadGridView

    3. Create Visual Studio Extention Package

        Project (VS Package)

    4. Add ToolWindow into VSPackage 

    5. That ToolWindow has above

        UserControl.

 And this VSPackage project make run.

Then you will see the problem.

If you sucess to run it, please send your demo to me.
