How to undo the covered ranges of the grid in WinForms GridControl?

Platform: WinForms |
Control: GridControl
Tags: undoredo

Undo Operation

By default, the covered ranges cannot be UNDO from the GridControl. This can be achieved by creating the custom GridModelSetCoveredRangesCommand derived from the GridModelCommand. The covered ranges have to be pushed to the command stack of the GridControl using the Push method of the CommandStack property.

The UNDO operation will reload the covered ranges once CTRL + Z key is pressed after the covered ranges is cleared from the GridControl.


public class GridModelSetCoveredRangesCommand
: GridModelCommand
    GridRangeInfoList ranges;
    bool setOrReset;
    private GridModelCoveredRanges cr;
    public GridModelSetCoveredRangesCommand(GridModelCoveredRanges cr, GridRangeInfoList ranges, bool setOrReset)
        : base(cr.Model)
        if (setOrReset)
        this.cr = cr;
        this.ranges = ranges;
        this.setOrReset = setOrReset;
    // Executes the command.
    public override void Execute()
        foreach (GridRangeInfo range in ranges)
        Grid.ScrollCellInView(ranges.ActiveRange, GridScrollCurrentCellReason.Command);



Public Class GridModelSetCoveredRangesCommand
 Inherits GridModelCommand
 Private ranges As GridRangeInfoList
 Private setOrReset As Boolean
 Private cr As GridModelCoveredRanges
 Public Sub New(ByVal cr As GridModelCoveredRanges, ByVal ranges As GridRangeInfoList, ByVal setOrReset As Boolean)
  If setOrReset Then
  End If
  Me.cr = cr
  Me.ranges = ranges
  Me.setOrReset = setOrReset
 End Sub
 ' Executes the command.
 Public Overrides Sub Execute()
  For Each range As GridRangeInfo In ranges
  Next range
  Grid.ScrollCellInView(ranges.ActiveRange, GridScrollCurrentCellReason.Command)
 End Sub
End Class


Undo and Clear the covered ranges

In the below sample, the covered ranges can be cleared by clicking the ‘Clear covered ranges’ button. And covered ranges can be added to the command stack collection by clicking the ‘Undo the covered ranges’ button. The covered ranges can be restored by pressing CTRL+Z.


//Adding Covered ranges
this.gridControl1.CoveredRanges.Add(GridRangeInfo.Cells(1, 1, 3, 3));
private void button2_Click(object sender, EventArgs e)
    GridRangeInfoList list = new GridRangeInfoList();
    list.Add(GridRangeInfo.Cells(1, 1, 3, 3));
    this.gridControl1.CommandStack.Push(new GridModelSetCoveredRangesCommand(this.gridControl1.Model.CoveredRanges, list, false));
private void button3_Click(object sender, EventArgs e)



'Adding Covered ranges
Me.gridControl1.CoveredRanges.Add(GridRangeInfo.Cells(1, 1, 3, 3))
private void button2_Click(Object sender, EventArgs e)
 Dim list As New GridRangeInfoList()
 list.Add(GridRangeInfo.Cells(1, 1, 3, 3))
 Me.gridControl1.CommandStack.Push(New GridModelSetCoveredRangesCommand(Me.gridControl1.Model.CoveredRanges, list, False))
private void button3_Click(Object sender, EventArgs e)
