and i have handled mouse click event in .cs file as follows

private void CellValuePresenter_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
if ((sender as CellValuePresenter).Record.IsActive && (sender as CellValuePresenter).Field.Index != 0 && (sender as CellValuePresenter).Field.Index != 4)
{
if (e.ClickCount == 2)
{
var presenter = sender as CellValuePresenter;
if (null != presenter)
{
if (presenter.Field.Index != 0 && presenter.Field.Index != 4)
{
presenter.Editor.StartEditMode();
}
else
{
return;
}
}
}
}
}

when click on any cell ,if it is single click ,it will select the row and if it is double click then corresponding cell become in edit mode.

the proplem is when i edit values in cell ,it is not effected in the binded collection in model view.

it is an urgent requirement.

if any idea pls share me,

Regards ,
