Hello all!

I'm using RadGridView 2013 Q3 SP2 to represent collection with grouping feature. Collection size is not over 100 entries.
I found a combination of groupped columns which cause ArgumentOutOfRangeException after i do any scroll: mouse wheel, page down, etc.
All of these columns are strings.
I can't reproduce this bug in sample application so may be it is data sensitive.
GridView has no RowStyles, no CellTemplates and isn't placed in a control that measures its children with infinity.

The bug don't occurs if don't set GroupRenderMode or use old Nested.

Here is stacktrace:
System.ArgumentOutOfRangeException: Argument is out of range. Parameter name: index
   at System.ThrowHelper.ThrowArgumentOutOfRangeException()
   at System.Collections.Generic.List`1.get_Item(Int32 index)
   at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.FlatLayoutStrategy.RealizeRows(Int32 startIndex, Int32 endIndex, Double& verticalOffset, HashSet`1& realizedRows)
   at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.FlatLayoutStrategy.MeasureOverride(Size availableSize)
   at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.MeasureOverride(Size availableSize)
   at System.Windows.FrameworkElement.MeasureCore(Size availableSize)
   at System.Windows.UIElement.Measure(Size availableSize)
   at System.Windows.ContextLayoutManager.UpdateLayout()
   at System.Windows.ContextLayoutManager.UpdateLayoutCallback(Object arg)
   ...


Here is RadGridView:
<telerik:RadGridView
                     ItemsSource="{Binding Entries}"
                     HorizontalAlignment="Stretch"
                     IsReadOnly="False"
                     AutoExpandGroups="True"
                     CanUserDeleteRows="False"
                     AutoGenerateColumns="False"
                     IsFilteringAllowed="False"
                     CanUserSortColumns="True"
                     GroupRenderMode="Flat"
                     ShowColumnSortIndexes="True"
                     RowIndicatorVisibility="Collapsed">
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Value1}" />
        ...

Hello Zber,

Thank you for the feedback.

I've tried to reproduce the problem but to no avail. Could you check the attached test project and modify it in order to achieve the exception?

Hello, Yordanka!

I'm not able to use your test project because the problem is dataset sensitive. I can reproduce it on numbers of datasets.
Here is my test project: https://drive.google.com/file/d/0B5w5QaLXOxYkQVFzOHhXREF5Tk0/edit?usp=sharing

You should drag three columns to start grouping: --First--, --Second--, --Third-- and you'll get exception.

Hi Zber,

Thank you very much for the project. 

I've logged the exception in our bug tracking system for further investigation. Also you can track its status from our Feedback portal. Here is the link to it. As a workaround you can change either GroupRenderMode to Nested or to enable row virtualization.

I've updated your Telerik points accordingly.

Hi Yordanka,

Thanks for points and ticket!
p.s. I got exception independently of EnableRowVirtualization value. I found that only Nested GroupRenderMode helps.

Zber

Hi Yordanka,

I see that ticket has been completed. How I can test that? Should I wait for next major release?

Hi Zber,

We resolved the exception and that's why the feedback status was set to Completed. The fix for it will be included in the Q1 2014 official version expected in the end of February.

Hello Zber,

I am writing to inform you about the exception progress. Unfortunately, the first fix we made didn't pass our tests so we will not be able to resolve it for Q1 2014 official version. We are still working on it and most probably it will be resolved with the first latest internal builds after Q1 2014 release.

Please excuse us for any inconvenience caused.

Yordanka
