How would I bind the Text of the hyperlink then?

I've tried this:

    
                Protected Sub grid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles grid.ItemDataBound 
        
                    If e.Item.DataItem IsNot Nothing Then 
        
                        'Set the hyperlink caption 
        
                        DirectCast(e.Item.OwnerTableView.Columns(2), Telerik.Web.UI.GridHyperLinkColumn).Text = DirectCast(e.Item.DataItem, InsightEcosystems.IEReports.IEReport).Tracking.Name 
        
                    End If 
        
                End Sub

However the names that get bound do not go into the right data rows.

In a simple example, the collection I'm binding to has two rows. When the grid renders the first row's hyperlink Text is still empty with the code above, and the second row's hyperlink Text is what should appear in the first row.

Further, I've noticed that ItemDataBound gets called 4 times with e.Item.DataItem <> Nothing when there are only 2 items in the collection. When I check e.Item.RowIndex it outputs 2, 3, 4, and 5 on each of the calls even though two rows visually appear in the grid when it renders.

Thanks again

Nevermind.

Here is the solution for others that have this same problem:

    
                Protected Sub grid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles grid.ItemDataBound 
        
                    If TypeOf e.Item Is Telerik.Web.UI.GridDataItem Then 
        
                        Dim gridDataItem As Telerik.Web.UI.GridDataItem = DirectCast(e.Item, Telerik.Web.UI.GridDataItem) 
        
                        DirectCast(gridDataItem("Name").Controls(0), HyperLink).Text = DirectCast(gridDataItem.DataItem, InsightEcosystems.IEReports.IEReport).Tracking.Name 
        
                    End If 
        
                End Sub

I now have a related problem with sorting. As described above, my hyperlink column doesn't contain a DataField value because the value it needs is nested in a sub-object. I'm having to catch the ItemDataBound event and set the Text on the hyperlink to the value in the nested sub-object.

Because of all of this, sorting doesn't work on the hyperlink column.

Is there a way to catch the SortCommand event and handle it? I'm not sure how.

Unless the other column types will support nested sub-objects VERY soon, it looks like anyone binding to an object hierarchy will just have to loop through them, copy them to an ArrayList, and then bind the grid to that.
