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

Search as you type logic does not update the grid items

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.

can you please expose when key enter is pressed on a grid? you're too selfish to just hid it for yourself! why do you make things so complicated for us?? 

Error ToolTip for InvalidEditableIndicator should be added to GridViewRow and TreeListViewRow.

This functionality will be available with Q2 2015.

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 Gridview Distinct Filters can't be reuse if the filtering panel is close.

When the filter panel is reopen selecting or deselecting distinct filter have no effect.

This is reproductible in telerik demo in any gridview with distinct filter.

the bug is present in browser and oob applications.

The issue should be resolved with Q2 2015 SP1.
