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 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
