WatermarkYou can achieve this by deriving the Grid and overriding the OnPaint method. During override, call the baseclass, and then use e.Graphics.DrawString to draw the string. C# public class MyGridControl : GridControl { public MyGridControl() { this.SmoothControlResize = false; } private bool isApproved = true; protected override void OnPaint(System.Windows.Forms.PaintEventArgs pe) { base.OnPaint(pe); if(isApproved) { string s = "Approved"; Brush br = Brushes.LightPink; StringFormat format = new StringFormat(); format.LineAlignment = StringAlignment.Center; format.Alignment = StringAlignment.Center; format.Trimming = StringTrimming.None; format.FormatFlags = StringFormatFlags.NoWrap; int orientation = -45; float angle = (float) orientation; Font fnt = new Font("Arial", 20, FontStyle.Bold | FontStyle.Underline); RotatePaint.DrawRotatedString(pe.Graphics, s, fnt, br, this.Bounds, format, angle); } } VB Public Class MyGridControl Inherits GridControl Public Sub New() Me.SmoothControlResize = False End Sub Private isApproved As Boolean = True Protected Overrides Sub OnPaint(ByVal pe As System.Windows.Forms.PaintEventArgs) MyBase.OnPaint(pe) If isApproved Then Dim s As String = "Approved" Dim br As Brush = Brushes.LightPink Dim format As New StringFormat() format.LineAlignment = StringAlignment.Center format.Alignment = StringAlignment.Center format.Trimming = StringTrimming.None format.FormatFlags = StringFormatFlags.NoWrap Dim orientation As Integer = -45 Dim angle As Single = CSng(orientation) Dim fnt As New Font("Arial", 20, FontStyle.Bold Or FontStyle.Underline) RotatePaint.DrawRotatedString(pe.Graphics, s, fnt, br, Me.Bounds, format, angle) End If End Sub After applying the properties, the Grid is displayed as follows.
