I am using the example from here http://www.telerik.com/community/forums/winforms/gridview/radgrid-sum-expression-for-child-data.aspx
to have a cell in my parent table (unbound) show the sum of the columns in a child grid. The problem I am running into is that ChildRows is off by 1. I.e. when CellValueChanged is called when I enter the amount, looks like the Row has yet to be added. Is there a better event to hook? I really want to update when the Row has been added.
Is CellValueChanged called before the ChildRows collection is updated?
private void gridExpenses_CellValueChanged(object sender, GridViewCellEventArgs e)
if (e.Column.OwnerTemplate != gridExpenses.MasterTemplate && e.Column.Name == "colAmount")
private void EvaluateTotal(GridViewRowInfo parent)
if (parent.ChildRows.Count > 0)
parent.Cells["colRemaining"].Value = gridExpenses.Evaluate("Sum(colAmount)", parent.ChildRows);
