  Hi,
  
  I have a grid with all default settings related with Sorting. 
  grid's ItemSource property is set to custom List<MyCalss> at run time. 
  But when i click on column's header for sorting it clears grid data.
  
  
  Thanks,
  Bala

  Got the issue.
  After leaving the context, i was clearing the data source collection assigned to GridView.ItemSource something like below -
  
  List<MyClass> obj = new List<MyClass>;
  try
  {
  //Populate obj here.
  this.gridview.ItemSource = obj;
  }
  catch(Exception)
  {}
  finally
  {
  obj.clear(); // This was the culprit
  }
