Example

This snippet demonstrates the GroupByRowExpansionStyle and GroupByRowInitialExpansionState properties on the UltraGridOverride class. These properties can be used to customize the way that users can expand GroupBy rows and whether GroupBy rows are initially expanded or collapsed.

Visual Basic

Imports Infragistics.Win.UltraWinGrid

Sub Form1_Load(sender As Object, e As System.EventArgs)
   ' Prevent expansion indicators from appearing in the GroupBy rows.  The end-user can 
   ' still expand the GroupBy rows via double-clicking or the keyboard.
   '
   Me.ultraGrid1.DisplayLayout.Override.GroupByRowExpansionStyle = GroupByRowExpansionStyle.DoubleClick
   
   ' Make it so that the GroupBy rows will automatically be expanded when a column is grouped.
   '
   Me.ultraGrid1.DisplayLayout.Override.GroupByRowInitialExpansionState = GroupByRowInitialExpansionState.Expanded
End Sub

C#

using Infragistics.Win.UltraWinGrid;

private void Form1_Load(object sender, System.EventArgs e)
{	
	// Prevent expansion indicators from appearing in the GroupBy rows.  The end-user can 
	// still expand the GroupBy rows via double-clicking or the keyboard.
	//
	this.ultraGrid1.DisplayLayout.Override.GroupByRowExpansionStyle = GroupByRowExpansionStyle.DoubleClick;

	// Make it so that the GroupBy rows will automatically be expanded when a column is grouped.
	//
	this.ultraGrid1.DisplayLayout.Override.GroupByRowInitialExpansionState = GroupByRowInitialExpansionState.Expanded;
}
