Hi, once radGridView is place in the content for RadExpander, Microsoft Visual Studio stopped working. Is there any problem with the code (attached as image) ?
Thank you for the provided picture. Still, I wasn't able to reproduce this behavior. Can you elaborate more on what do you mean by "Microsoft Visual Studio stopped working"? Is the VS hang or the VS Designer throw exception? Attached to this reply is the project which I used to test your scenario based on the provided picture. Can you give this project a try and let me know if I am missing something in order to reproduce this behavior. In addition, in the attached picture the RadGridView control is placed in Grid.Row with Height set to star. Keep in mind that placing the RadGridView in controls/panels which measure its content with infinity, will turn off the UI Virtualization. You can read useful performance tips for the RadGridView control in the Tips and Tricks help article in our documentation.
