Expand functionality in Grouping grid

[Prathima Venkobachar]

Hi,

Can I do expand of only the selcted grouped rows in a grouping grid..?
If I use Groupinggrid.Table.ExpandAllGroups(); It expands all the grouped rows.
I want to expand only highlighted or selected grouped row.Is there any method to do this..?

Thx in advance,
Prathima

Given a Group g, you can expand or collapse it by setting g.IsExpanded to true or false. Same is true for a GridRecord r using r.IsExpanded. (You can also use teh Record.SetSelected method too.)

Here is a little button handler that will expand all selected records in a nested table.

private void button1_Click(object sender, System.EventArgs e)
{
	this.gridGroupingControl1.Table.CollapseAllRecords();
	foreach(SelectedRecord r in this.gridGroupingControl1.Table.SelectedRecords)
	{
		r.Record.IsExpanded = true;
	}
}

Thx for the reply.
I have 10 grouped rows.I hv expanded 3 grouped rows.I have selected the record in the first grouped row.Now if I click expangOnlySelected group, I get selectedrecords count zero.

I assume selected reocrd is nothing but selected row inside a grouped row.

Thx,

I do not know what ''expangOnlySelected'' is.

To use gridGroupingControl1.Table.SelectedRecords, make sure you have set:

this.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.None;
this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.One;//something other than None.

''expangOnlySelected'' is a btn I hv in the form. Onclick of this, I shd expand only one grouped row which is selected.
still I get gridGroupingControl1.Table.SelectedRecords count zero.
