Grid Undo command.stack virtual grid

[Smitha]

Hi,

My gridcontrol for windows forms is not doing the undo functionality.

void GridSaveCellInfo(object sender, GridSaveCellInfoEventArgs e)
{
theGrid.CommandStack.Enabled = true;
if (e.ColIndex > 0 && e.RowIndex > 0)
{
//do something
if (e.ColIndex % 2 == 1)
{
// Convert a CellValue to the desired type using Syncfusion 'Convert' class.
DateTime dttm = (DateTime)GridCellValueConvert.ChangeType(e.Style.CellValue, typeof(DateTime), null);

// Debug.Assert(dttm == (DateTime)e.Style.CellValue);
//do something
}
else
{
// Convert a CellValue to the desired type using Syncfusion 'Convert' class.
float value = (float)GridCellValueConvert.ChangeType(e.Style.CellValue, typeof(float), null);
// Debug.Assert(value == (float)e.Style.CellValue);
//do something
}
}
e.Handled = true;
}

private void UndoCellsToolStripMenuItem_Click(object sender, EventArgs e)
{

if (!this.theGrid.CommandStack.InTransaction)
{
this.theGrid.CommandStack.Undo();
ShowStacks();
}
}

Where should i enable commandstack= true?
My grid's data is first in a middle layer(data array) and then relects in the grid.
So Any changes i make to the grid are reflceted in the data array.

Thank you
SC

Hi Smitha,

 

Thank you for your interest in Syncfusion products,

 

The undo operation and the redo operation can be achieved from the CommandStack object of the GridControl, which is retrieved from the table control base.

 

Please refer the UG documentation from the below location:’

Also refer the forum from the below link which show case the implementation of the behavior in virtual grid:
