cell events

[Catinat Velmourougan]

{this.txtPreview.Text = this.Collection.Expression;
this.txtPreview.Text = this.BuildingExpression;
if(e.Range.Right == 3) {
this.grdFilter.RowCount = this.grdFilter.RowCount + 1;

}
Kindly refer the code above ,
I have written the above code inside the grd_cellschanged event.
The code block throws the stack overflow exception.
The exception is because the rowcount change calls the cellschanged event again."e" is of GridCellsChangedEventArgs
type.
Requirement:
The grid has 3 cols.
The no of rows is variable.
I want to add an new row to the grid after the contents of 3rd col have been cahnged in every row.

Do you want to add the new row as your user leaves the cell in column 3 after changing its value?

If so, try doing it in the CurrentCellvalidating event.

private void gridControl1_CurrentCellValidating(object sender, CancelEventArgs e)
{
	GridCurrentCell cc = this.gridControl1.CurrentCell;
	if(cc.ColIndex == 3)
	{
		cc.Lock();
		this.gridControl1.RowCount += 1;
		cc.Unlock();
	}
}
