Displaying Non-Scrolling Summaries

The WinGrid™ displays summaries at the bottom of the row collection by default. In addition, the summaries scroll as rows are scrolled.

This topic shows you how to fix the summaries so they don’t scroll. It also describes how to show summaries at the top of the row collection rather than at the bottom.

Note
Note

The summaries will be fixed in the root band only. Child bands will display the summaries, however, they will scroll.

To display non-scrolling summaries:

  1. Before you start writing any code, you should place using/imports directives in your code-behind so you don’t need to always type out a member’s fully qualified name.

In Visual Basic:

Imports Infragistics.Win.UltraWinGrid

In C#:

using Infragistics.Win.UltraWinGrid;

  1. Set the SummaryDisplayArea to a value that has either BottomFixed or TopFixed bit turned on. The SummaryDisplayArea property is a flagged enumeration type. You can specify multiple values by using the bitwise or operation.

In Visual Basic:

Private Sub CustomersUltraGrid_InitializeLayout(ByVal sender As System.Object, _
  ByVal e As Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs) _
  Handles CustomersUltraGrid.InitializeLayout
	Me.CustomersUltraGrid.DisplayLayout.Override.AllowRowSummaries = _
	  AllowRowSummaries.True
	Me.CustomersUltraGrid.DisplayLayout.Override.SummaryDisplayArea = _
	  SummaryDisplayAreas.TopFixed
End Sub

In C#:

private void customersUltraGrid_InitializeLayout(object sender,
  Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
{
	this.customersUltraGrid.DisplayLayout.Override.AllowRowSummaries =
	  AllowRowSummaries.True;
	this.customersUltraGrid.DisplayLayout.Override.SummaryDisplayArea =
	  SummaryDisplayAreas.TopFixed;
}
Note
Note

that the SummaryDisplayArea property is exposed off the SummarySettings object as well so different summaries can be displayed in different areas.

  1. The below screen shot shows an UltraGrid with fixed summaries at the top. When you scroll the rows are scrolled out of view at the top however the summary area remains visible at all times.
