I am using version 2015.1.401.40 of the ASP.NET controls for AJAX.
I am hiding the expand / collapse icon for mastertable rows where the detailed table has no rows. I am also setting the detail table to visible false. I'm doing both of these in the DetailTableDataBind like so:
e.DetailTableView.Visible = False
parentItem("ExpandColumn").Controls(0).Visible = False
I want the users to be able to expand and collapse all rows that have child data, so I added this property to the RadGrid: EnableHierarchyExpandAll="true"
However, that expands EVERY SINGLE ROW, even the rows where I've removed the expand / collapse button and set the detail table to invisible.
Question: Is there any way I can expand ONLY the rows that have an expand / collapse icon (only the rows that actually have detail data)?
