Can I expand / collapse only the rows that have data in their detail tables?

[Brent Hetland]

Hi,
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)?

I've looked a bit at the javascript you all use _expandAll, but don't think I can implement what I want to do...

Thanks,

Brent

Hello Brent,

I've already provided a reference link in the following forum:

I suggest that we continue our conversation in the mentioned thread.
