I have created a grid view and I am trying to group the items together. I think maybe this is a bug in the older version (v. 2010.3.10.1215) I am using. The problem is when I click on the expand button in the grid the winform locks up compltely and I have to end the program. When I remove the self reference I see the grid is built out properly with reference to my IDs and ParentIDs. The DataSource of my datagrid is a DataTable that I am building via code.
this.radGridView1.Relations.AddSelfReference(this.radGridView1.MasterTemplate, "Id", "ParentId");
Did I do something wrong or is this a known bug?

Looks like it is hanging up on Telerik.WinControls.UI.GridViewHierarchyRowInfo according to the profiler trace. Also hanging on call to Telerik.WinContruls.UI.GridDataCellElement.
I clicked the expand button in the grid and I just waited and waited. Nothing ever happened and I ran through the debugger to ensure it wasn't any code I wrote (could be missing setting something on the grid).

As a quick follow up, I have now resolved this and found the root cause. I had made the assumption that the ID field in the data I was pulling from was an INT but it was actually a STRING to my suprise. The problem was that my ID table was a STRING and my ParentId table was an INT. The parent rows would be loaded normally but when I clicked to expand the child rows the application would hang without any error. This was clearly a type conversion issue and I have resolved this by casting the ID to and INT. If anybody ever runs into this issue make sure that the same data type is used for the self reference.
