I'm using a RadGrid using a DataSet as the data source, and am setting AutoGenerateHierarchy to true.  When trying to expand a row having a large number of child rows (several thousand), the rows are never expanded (I've given up after waiting several minutes.)  However, I can copy those child rows into a new DataTable, display them in an new RadGrid control, and it only takes a few seconds for them to be displayed. 

Am I exceeding the limits on what can be displayed in a hierarchical gridview?

Hello Robert,

Thank you for writing.

It is a known issue with our RadGridView in hierarchical mode. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - Feedback Item

Currently, the possible solution that I can suggest is to set the RadGridView.UseScrollbarsInHierarchy property to true (which reduces the load time for the hierarchy rows considerably on my end) or use the Load-On-Demand Hierarchy approach.

I hope this information helps. Should you have further questions, I would be glad to help.

Regards,

Setting UseScrollbarsInHierarchy to true provides a huge improvement.

Thanks!
