Nov 13, 2018

The following sample code handles the TreeList.NodeCellStyle event to modify the appearance of the “Budget“ column’s cells whose values are greater than 500,000.

C#
VB.NET

csharp

using DevExpress.XtraTreeList;

private void treeList1_NodeCellStyle(object sender, GetCustomNodeCellStyleEventArgs e) {
   // Modify the appearance settings used to paint the "Budget" column's cells
   // whose values are greater than 500,000.
   if (e.Column.FieldName != "Budget") return;
   if (Convert.ToInt32(e.Node.GetValue(e.Column.AbsoluteIndex)) > 500000) {
      e.Appearance.BackColor = Color.FromArgb(80, 255, 0, 255);
      e.Appearance.ForeColor = Color.White;
      e.Appearance.FontStyleDelta = FontStyle.Bold;
   }
}

Imports DevExpress.XtraTreeList

Sub TreeList1_NodeCellStyle(sender As Object, e As DevExpress.XtraTreeList.GetCustomNodeCellStyleEventArgs) Handles TreeList1.NodeCellStyle
   ' Modify the appearance settings used to paint the "Budget" column's cells
   ' whose values are greater than 500,000.
   If e.Column.FieldName <> "Budget" Exit Sub
   If Convert.ToInt32(e.Node.GetValue(BudgetColumnID)) > 500000 Then
      e.Appearance.BackColor = Color.FromArgb(80, 255, 0, 255)
      e.Appearance.ForeColor = Color.White
      e.Appearance.FontStyleDelta = FontStyle.Bold
   End If
End Sub
