How to sort columns in Infragistics WinGrid

This code demonstrates how WinGrid allows the user to sort on both single and multiple columns by clicking on the column headers. The UltraWinGrid allows user to sort by setting the .HeaderClickAction property to either .SortSingle or .SortMulti.

Below are the steps to achieve the same

1. Adding using/imports directives
VB:

Imports Infragistics.Win.UltraWinGrid

C#:

using Infragistics.Win.UltraWinGrid;

2. The InitializeLayout event of UltraGrid sets the default HeaderClickAction for all bands and all columns

VB:

Private Sub UGSort_InitializeLayout(ByVal sender As Object, _
  ByVal e As Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs) _
  Handles UGSort.InitializeLayout
   e.Layout.Override.HeaderClickAction = HeaderClickAction.SortSingle
End Sub

C#:

private void UGSort_InitializeLayout(object sender, 
  Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
{
 e.Layout.Override.HeaderClickAction = HeaderClickAction.SortSingle;
}

3. The code in the Button Click event instructs the UltraWinGrid to sort on band 1 column 2 in Descending order

Visual Basic:

Private Sub btnSortBand1Column2_Click(ByVal sender As System.Object, _
  ByVal e As System.EventArgs) Handles btnSortBand1Column3.Click
 Me.UltraGrid1.DisplayLayout.Bands(1).Columns(2).SortIndicator = _
   SortIndicator.Descending
End Sub

C#:

private void btnSortBand1Column2_Click(object sender, EventArgs e)
{
 this.ultraGrid1.DisplayLayout.Bands[1].Columns[2].SortIndicator = 
   SortIndicator.Descending;
}
