Gridcontrol - RowEvents

[Ravichandran]

Hi,

Is there any event which will be fired once we move from one row to next row or some other row in GRIDCONTROL not in BoundGrid Control.?

There are row related events but those are for Range of Rows only.

Thanks & Regards

Hi Calvin,

Fine. But I am getting an exception in paint event if i move from one row to other. But not getting this exception frequently.

pls have a look of my code

private void EditableGrid_CurrentCellMoving(object sender, GridCurrentCellMovingEventArgs e)
{
GridCurrentCell currentCell =this.CurrentCell;

if(currentCell.RowIndex != e.RowIndex)
{
if(m_document.IsDirty)
{
if ( RowChanged != null )
{
m_document.IsDirty = false;
RowChanged(currentCell.RowIndex-1);
}
}
}

}

and also written some code in

private void EditableGrid_SaveCellInfo(object sender, GridSaveCellInfoEventArgs e)
{
GridCurrentCell currentCell =this.CurrentCell;
//currentCell.BeginEdit();
if (e.RowIndex > 0 )
{
int row = e.RowIndex-1;
if (m_document[row, e.ColIndex] != e.Style.CellValue)
{
m_document[row, e.ColIndex] = e.Style.CellValue;
m_document.IsDirty = true;

}
e.Handled = true;
}
//currentCell.EndEdit();
}

Regards
Ravi

Hi Ravi,

Have a check that the row index must be greater than -1 in the CurrentCellMoving event handler to see if that avoids the mentioned paint issue.

private void EditableGrid_CurrentCellMoving(object sender, GridCurrentCellMovingEventArgs e)
{
if(e.RowIndex > -1)
{
GridCurrentCell currentCell =this.CurrentCell;

if(currentCell.RowIndex != e.RowIndex)
{
if(m_document.IsDirty)
{
if ( RowChanged != null )
{
m_document.IsDirty = false;
RowChanged(currentCell.RowIndex-1);
}
}
}
}

}

Hi Ravi,

Sorry, I am not able to reproduce the issue here. Can you set Break into the debugger when the exception is thrown and find exactly where the exception is being thrown? Or if you can reproduce the issue in the sample in the above mentioned forum thread and send it back we can get back soon with a solution.

Calvin.
