Scrollviewer is not updated when row details are collapsed.

When you place a DataTrigger whithin a CellTemplate, it is being ignored by RadGridView for WPF

Workaround ( until fixed ) - set the ContentTemplate of the cell via Style in a static resource instead.

If you have the following model, the columns that show the Test and Date properties (in the derived class) cannot be sorted or filtered. Also, no header text is displayed.

 

To work this around, set the IsCustomSorting property of the corresponding columns and implement a custom sorting in the Sorting event of RadGridView.

 

The exception message is: "... is not a valid metadata type for type filtering operations. Type filtering is only valid on entity types and complex types." The exception is observed when using AggregateFunctions and setting up the data with EntityFramework. 

The problem occurs from 2014 Q2.  It should be resolved with lib version 2014.3.1319.

Columns with * width are not measured correctly when GridView is placed in ScrollViewer and its width is changed.

Just run the attached project and scroll horizontally to the very end several times (at least two times).
I tried disabling the column virtualization but this did not help.

This issue will be resolved with Q2 2015. 
A new virtualization mechanism for ColumnGroups will be introduced with Q2 2015. A property EnableColumnGroupsVirtualization is exposed with default value True for enabled virtualization. Setting it to False will enable the old logic. 

Scrollbar scrolls unexpectedly when column width is changed. Check the following video for a reference:

Version 2016.3.1024.45 (from nuget packages, if that matters)
Adding a new row with the "Add new row" button and then clicking the row indicator results in an extra row. Demo: http://recordit.co/Nn8y2z2YpI

Available in the R1 2017 SP1 Release.

There are cells exported for the group rows, but they are empty. If you define ColumnGroupDescriptors instead GroupDescriptors, then the exported data is the correct one.

Border is not correct when FilterRow is on and Column header is wrapped. Sample and Screenshot attached.

The group panel item image of a column with custom header is blurred

When you define a style targeted at GridViewCell with a color without transparency, horizontal grid lines are hidden.
