How to enable or disable buttons based on undo or redo operations in WinForms GridControl?

Undo redo operation

To enable or disable buttons based on the Undo or Redo operations, check the CommandStack.UndoStack and CommandStack.Redo properties. When the count of the CommandStack is greater than zero, you can enable or disable those buttons.

The following code demonstrates the same.

void gridControl1_CellsChanged(object sender, GridCellsChangedEventArgs e)
{
    //Enables or disables Undo and Redo buttons.
    if (this.gridControl1.CommandStack.UndoStack.Count > 0)
    {
        this.BtnUndo.Enabled =this.gridControl1.CommandStack.UndoStack.Count > 0 ;
    }

    if (this.gridControl1.CommandStack.RedoStack.Count > 0)
    {
        this.btnRedo.Enabled = this.gridControl1.CommandStack.RedoStack.Count > 0;
    }
}

Private Sub gridControl1_CellsChanged(ByVal sender As Object, ByVal e As GridCellsChangedEventArgs)
    'Enables or disables Undo and Redo buttons.
    If Me.gridControl1.CommandStack.UndoStack.Count > 0 Then
      Me.BtnUndo.Enabled =Me.gridControl1.CommandStack.UndoStack.Count > 0
    End If

    If Me.gridControl1.CommandStack.RedoStack.Count > 0 Then
      Me.btnRedo.Enabled = Me.gridControl1.CommandStack.RedoStack.Count > 0
    End If
End Sub
