Hi Francis,

Hi Yohan,

There is no way to use a single ColumnLayout object for the root and for the children and then have the HeaderVisibility be set differently on each level.  A solution to this would involve separate ColumnLayout objects for parent and children.

Hi Francis,

Thanks for the info.  Would this mean that column moving, sorting, resizing, etc. would be seperate for each ColumnLayout?  If so, that would complicate things...

The data would be the same in both layouts, I just need to have a single header for all items and have expandable rows.  Do you have any other suggestion?

Thanks

Yohan

Hi Yohan, 

Thats correct, you've have to manually sync moving, sorting, and resizing, for each additional ColumnLayout. 

Although it should be possible via the events exposed for each of the features.

Hi Stephen,

Thanks for confirming my worst fears... ;)  Do you guys have a code example of this lying around?  

I Hope this could be a future improvement for the XamGrid.  Let's admit that self referencing data doesn't necessarily need to have repeating column headers if they all say the same thing.  I like how the sample on the Infragistics web site is tricked so we don't see this... :)  

Cheers,

Yohan

Hey Yohan, 

Actually, i had another idea, which you may want to try (keep in mind i haven't tried it yet)

If you use the approach of 1 ColumnLayout, you could listen to the IntializeRow event and try the following code: 

 void grid_InitializeRow(object sender, InitializeRowEventArgs e)
        {
            if (e.Row.Level != 0)
            {
                RowsManager manager = e.Row.Manager as RowsManager;
                if (manager != null)
                    manager.HeaderRow.Height = new RowHeight(0);
            }
        }

Hi Stephen,

I tried your solution... Almost!  The only thing that is buggy is that the header appears momentarily and then dissapears.  I'll try to figure out how to hide the row until it's header has been hidden...
