Columns and column groups get misaligned after restoring GridView settings using Persistence Framework as column groups do not get re-rendered. 

Resolved with LIB version 2014.1.414

A GridViewExpressionColumn is added to a grid with columns bound to indexer properties, i.e.:Values["RC1"], Values["RC2"], etc. 

The expression column should calculate a similar formula: Values["RC1"]/Values["RC2"]*100. The formula is successfully parsed as a NodeExpression, however, no calculations are made.

GridViewExpressionColumn cell does not update its content when editing it, CellEditTemplate is used and the datacontext is an object which implements IEditableObject interface.

The problem should be resolved with lib version 2015.3.1026.

The issue is replicated only when a filtering operation is applied. For a grouping and sorting one it is not. In Silverlight when the new source collection is set, the column headers are cleared and empty rows are displayed. In WPF the item is not cleared. The workaround is to clear the FilterDescriptors collection of RadGridView before assigning the new instance of the source collection.

The issue should be resolved with Q2 2015 SP1.

Should be resolved with Q2 2015 SP1.

In addition the AutoExpandGroups="False" is not respected and it only occurs when the GroupRenderMode is set to "Nested". As a workaround you can set the GroupRenderMode to "Flat".

- Add text box and RadGridView to silverlight app
- Add one editable row and multiple read only rows after that to a RadGridView. 
- Go to last cell of first row and double click for edit mode.
- Press tab

Focus should go to text box, instead silverlight hangs.

Find attached sample application where this can be reproduced.
