How to Change the Mouse Cursor in Windows Forms Grid Control

18 Nov 20181 minute to read

Introduction

The simplest way is to derive the grid and override OnSetCursor. You can add additional checks to narrow down where to set the cursor.

C#

//GridDataBoundGrid.
public class MyGridControl : GridControl 
{
  protected override void OnSetCursor(ref Message m)
  {
      base.OnSetCursor(ref m);

	//Always set the cursor to a cross.
      Cursor.Current = Cursors.Cross;

	//or
	
	//Put special cursor over cell 2,2.
	
	//Point pt = this.PointToClient(Control.MousePosition);
	
	//int row, col;
	
	//if(this.PointToRowCol(pt, out row, out col, -1)
	
	//        && row == 2 && col == 2)
	
	// {
	
	//        Cursor.Current = Cursors.Cross;
	
	// }

  }

}

VB.NET

Public Class MyGridControl
    Inherits GridControl 'GridDataBoundGrid
    Protected Overrides Sub OnSetCursor(ByRef m As Message)
    MyBase.OnSetCursor(m)
   
	'Always set the cursor to a cross.
     Cursor.Current = Cursors.Cross

	'OR
	'Put special cursor over cell 2,2.
	'Point pt = this.PointToClient(Control.MousePosition);
	'int row, col;
	'If Me.PointToRowCol(pt, row, col, -1) AndAlso row = 2 AndAlso col = 2 Then
    'Cursor.Current = Cursors.Cross;
	'End If
End Sub 
'MyGridControl 
End Class
