I don't know , for some reason, when I drag a column header to group panel, all the rows of the grid vanish leaving only group panel visible which is unresponsive. 

Figure 1 is the original gird. 

When I try to drag any column (say Year) to the group panel, Figure 2 is the result.

 Your help in solving this problem is highly appreciated.

Hello Rouf,

Based on the screenshots it would be hard to guess the exact cause of the issue.

However, one possible reason is the data-binding of RadGrid. Please make sure that you are using advanced data binding. You can use either declarative data source or provide the data via the NeedDataSource event. Check out the following articles that elaborate in more detail for both approaches.

With that said, make sure not to use simple data binding. Remove all calls to DataBind() from the code-behind.


Try to apply the modifications and see how the behavior changes. In case the issue persists please send the markup of the page with the related code behind so we can examine it.
