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".

The problem should be resolved with lib version 2015.3.1026.

Should be resolved with Q2 2015 SP1.

The issue should be resolved with Q2 2015 SP1.

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.

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
