There is not enough information to figure out what your problem is. I would put a breakpoint in in the doubleclick and see what your situation really is

Thank you and you're welcome ;)
you cannot typecast dynamic objects. the two have to be identical for them to be mapped correctly.

i'd suggest you try using the listbox itemsource to retrieve the records that you want. something

like:

C#
private void dtstuff_PreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
...

stuffdt sd = {DataGridItemSource}[dtstuff.SelectedIndex]; 

//assuming the datagriditemsource is a list of type stuffdt

...
}

the " { ... } " meant you had to replace the entire {DataGridItemSource} with the variable or view model where your data grid is getting it's values.
