How can i add row mouse double click to my user control that has a data grid in it

i did it with some bad way that i used data grid mouse double click event and some bug happened in this way but i want know simple and standard way

i also add double click event to data grid items in row_load event but it seems make my program slow if data grid has big source

private void dataGrid1_LoadingRow(object sender, DataGridRowEventArgs e)
{
    e.Row.MouseDoubleClick += new MouseButtonEventHandler(Row_MouseDoubleClick);
}

You can handle the double-click on the DataGrid element, then look at the event source to find the row and column that was clicked:

private void DataGrid_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    DependencyObject dep = (DependencyObject)e.OriginalSource;

    // iteratively traverse the visual tree
    while ((dep != null) && !(dep is DataGridCell) && !(dep is DataGridColumnHeader))
    {
        dep = VisualTreeHelper.GetParent(dep);
    }

    if (dep == null)
        return;

    if (dep is DataGridColumnHeader)
    {
        DataGridColumnHeader columnHeader = dep as DataGridColumnHeader;
        // do something
    }

    if (dep is DataGridCell)
    {
        DataGridCell cell = dep as DataGridCell;
        // do something
    }
}

I describe this in detail in this blog post that I wrote.
