How to: Provide Custom Display Text for Data Cells

The following example demonstrates how to provide custom display text for data cells via the ColumnView.CustomColumnDisplayText event. In the example empty strings are displayed within the "Discount" column's cells if they contain zero values.

The result is shown below:

 

C#

using DevExpress.XtraGrid.Views.Base;

 

private void gridView1_CustomColumnDisplayText(object sender,

CustomColumnDisplayTextEventArgs e) {

   if(e.Column.FieldName == "Discount")

      if(Convert.ToDecimal(e.Value) == 0) e.DisplayText = "";

}

 

VB

Imports DevExpress.XtraGrid.Views.Base

Private Sub GridView1_CustomColumnDisplayText(ByVal sender As Object, _

ByVal e As CustomColumnDisplayTextEventArgs) Handles GridView1.CustomColumnDisplayText

   If e.Column.FieldName = "Discount" Then

      If e.Value = 0 Then e.DisplayText = ""

   End If

End Sub
