How to expand a particular group selectively?

The IsExpanded property of a particular Goup should be set as true to make a grop expanded. Please refer the below code snippet which illustrates this:

C#

//Group by Col3

this.GridGroupingControl1.TableDescriptor.GroupedColumns.Add("Col3");

//Expand only the first group

this.GridGroupingControl1.Table.TopLevelGroup.Groups[0].IsExpanded = true;

VB

'Group by Col3

Me.GridGroupingControl1.TableDescriptor.GroupedColumns.Add("Col3")

'Expand only the first group

Me.GridGroupingControl1.Table.TopLevelGroup.Groups(0).IsExpanded = True
