title: WPF Stackpanel inside DataGrid Cell
body: <p>I have got a WPF Application, which contains a Window, inside it there is a DataGrid. On Startup, the DataGrid is completely empty, its Columns are created at runtime by code.</p>
  
  <p>I'm binding to a DataTable. The first coloumn is a single Text Field. I need to show one more Cell per Row, but as a Stackpanel, which itself holds some UserControls.</p>
  
  <p>Actually I'm trying to first insert a blank column as placeholder for my StackPanel and later insert a StackPanel from Code to each Cell.</p>
  
  <p>Unfortunately i don't get it running for some reasons. I cannot put a new Item to the Cell. Can anybody help me, please?</p>
  
  <p>Best Regards,</p>
