title: Possible to insert a new row in a silverlight datagrid from the UI? or only by modifying the datasource?
body: <p>In WinForms it was possible to add a new row to the grid by using the last row in the grid, some grid controls provide such functionality through the Insert button.</p>
  
  <p>Is this possible with the datagrid included with silverlight?</p>
  
  <p>My only available option is providing input controls to the user with a insert button and manually adding a new row to the collection.</p>
