GridViewSerialization example works fine as long as we have 1 gridView .In my case , i have TreeView and each treeviewitem is having
one gridview. Its something like that :

 <telerik:RadGridView x:Name="RadGridView1"  telerik:PersistenceManager.StorageId="RadGridView1".
<telerik:RadGridView x:Name="RadGridView2"  telerik:PersistenceManager.StorageId="RadGridView2".
<telerik:RadGridView x:Name="RadGridView3"  telerik:PersistenceManager.StorageId="RadGridView3".


After Saving Sorting on each grid , when i try to load then it gives me "null exception" for column . If you can extend your example of 
GridViewSerialization with multiple gridview then you can reproduce this issue.

I think i solved it by using if (column != null).

  if (column != null)
                    {
                        gridView.SortDescriptors.Add(new ColumnSortDescriptor() { Column = column, SortDirection = proxy.SortDirection });
                    }

Hi Aamir,

It seems that when loading, the saved column info cannot resolve its actual column in the GridView. It could be that the columns of the GridView have not already loaded or the column does not exist in the GridView. You can troubleshoot this with the custom provider class and check whether all of the GridView columns are loaded when the sort descriptors are being restored.
