Nested grids and InsertNewRow issue

[vk]

Hi,

I have a parent grid and a child one declared in the HierarchyChildTemplate. Both grids have ShowInsertRow set to true. If I click on the insert row panel in the inner grid and then click on the insert row panel in the parent grid, both rows go to an endless refreshing process and start flickering showing validation error signs...

Update: here is how I workarounded the issue:

void GridView_AddingNewDataItem(object sender, GridViewAddingNewEventArgs e)
{
   var grid = e.OwnerGridViewItemsControl;
   if (grid.Name == "parentGridView")
   {
      var childGrid = grid.ChildrenOfType<RadGridView>().Where(g => g.Name == "childGridView").SingleOrDefault();
      if (childGrid != null && childGrid.RowInEditMode is GridViewNewRow) childGrid.CancelEdit();
   }
   else if (parentGridView.RowInEditMode is GridViewNewRow) parentGridView.CancelEdit();
}
