Adding on Grid : CellEditEnded & RowEditEnd when building XAML dynamically.

Hello.
I was trying with success building a grid on SL4 by XAML (on datagrid control)
like this :

DataGridColumn gt;
DataTemplate dt;
StringBuilder CellTemp = new StringBuilder();
CellTemp.Append("&lt;DataTemplate ");
CellTemp.Append("xmlns='http://schemas.microsoft.com/winfx/");
CellTemp.Append("2006/xaml/presentation' ");
CellTemp.Append("xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' ");
CellTemp.Append("&lt;TextBox ");
CellTemp.Append("Text='{Binding myElement, Mode=TwoWay}'&gt;&lt;/TextBox&gt; ");
CellTemp.Append("&lt;/DataTemplate&gt;");
gt = new DataGridTemplateColumn();
dt = (DataTemplate)XamlReader.Load(CellTemp.ToString());
((DataGridTemplateColumn)(gt)).CellTemplate = dt;

Also adding events for KeyDown like on the forum :

But I cannot capture, for some reason CellEditEnded & RowEditEnded events (the cells are auto - editing).
I think not doing the cells auto-edit, but doing this on some other trickery, like : CurrentCellChanged on the grid & doing this.BeginEdit();

But, finally - how can I capture the CellEditEnded & RowEditEnded events, and can I eliminate the auto-edit behaviour of DataGrid cells when adding them by XAML dynamically (DataGridTemplateColumn on code).

Thanks. :).

This is happening because you have specified CellTemplate as TextBox which will never bring your grid to editmode.
(This is why you cells are auto editing.)

You can Use TextBlock for CellTemplate and TextBox for CellEditingTemplate. Something similar to below.

This will enable your grid to trigger event(s) required.

XML

DataGridColumn gt;
            DataTemplate dt, dtEdit;
            StringBuilder CellTemp = new StringBuilder();
            CellTemp.Append("<DataTemplate ");
            CellTemp.Append("xmlns='http://schemas.microsoft.com/winfx/");
            CellTemp.Append("2006/xaml/presentation' ");
            CellTemp.Append("xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>");
            CellTemp.Append("<TextBlock ");
            CellTemp.Append("Text='{Binding myElement, Mode=TwoWay}'></TextBlock> ");
            CellTemp.Append("</DataTemplate>");

            StringBuilder CellEditTemp = new StringBuilder();
            CellEditTemp.Append("<DataTemplate ");
            CellEditTemp.Append("xmlns='http://schemas.microsoft.com/winfx/");
            CellEditTemp.Append("2006/xaml/presentation' ");
            CellEditTemp.Append("xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>");
            CellEditTemp.Append("<TextBox ");
            CellEditTemp.Append("Text='{Binding myElement, Mode=TwoWay}'></TextBox> ");
            CellEditTemp.Append("</DataTemplate>");
            gt = new DataGridTemplateColumn();
            gt.Header = "Some Text";
            dt = (DataTemplate)XamlReader.Load(CellTemp.ToString());
            dtEdit = (DataTemplate)XamlReader.Load(CellEditTemp.ToString());
            ((DataGridTemplateColumn)(gt)).CellTemplate = dt;
            ((DataGridTemplateColumn)(gt)).CellEditingTemplate = dtEdit;
