RadGridView Group Panel not resize after remove all group panel items

[Per]

I'm using version v.2014.1.331.45.
I'm use RadGridView with dynamic row item.

<telerik:RadGridView Name="RadgridHoover"
                                     DockPanel.Dock="Top"
                                     BorderThickness="1,0,0,0"
                                     BorderBrush="LightGray"
                                     CanUserDeleteRows="True"
                                     CanUserInsertRows="True"
                                     ShowColumnHeaders="True"
                                     ShowGroupPanel="{Binding IsShowGroupPanel, Mode=TwoWay}"
                                     AlternateRowBackground="WhiteSmoke"
                                     AlternationCount="2"
                                     AutoGenerateColumns="False"
                                     SelectionMode="Multiple"
                                     IsReadOnly="True"
                                     IsFilteringAllowed="True"
                                     EditTriggers="CurrentCellClick"
                                     SelectionUnit="FullRow"
                                     EnableColumnVirtualization="False"
                                     EnableRowVirtualization="True"
                                     RowIndicatorVisibility="Collapsed"
                                     GridLinesVisibility="Both"
                                     behaviors:GridColumnsBindingBehavior.Columns="{Binding Columns, Mode=TwoWay}"
                                     ItemsSource="{Binding MembersTable, Mode=TwoWay}"
                                     SelectedItem="{Binding SelectedItem}"
                                     caliburn:Message.Attach="[Event SelectionChanged] = [Action MembersGridSelectionChanged($executionContext)];[Event DataLoaded] = [Action GridDataLoaded($executionContext)];[Event LoadingRowDetails] = [Action LoadingRowDetails($executionContext)]"
                                     DataLoadMode="Asynchronous"
                                     >
            </telerik:RadGridView>

The issue is when i group by a column, then i remove item in group panel, the size of group panel is not resize correctly.

See the image is attached.

Hi,

I've tried to reproduce the problem you report, but to no avail. You can check the attached sample project which illustrates my attempt. Please note that, I am using your version - 2014.1.0331.45. May I ask you to test with our latest version and let me know about the result? If the problem persists, I would ask you to send us a sample project that we can debug on our side, so that we would be able to identify the source.

Hello Thinh,

Thanks to the provided sample project we were able to reproduce the issue. However, we will need a little more time to further investigate the matter.

We will contact you as soon as we are done.

Hello,

We had investigated this in greater details. Here are our findings:

As it turns out this is not a bug but an expected behavior. Basically, when you group the grid, a GroupIndicator is shown and the grid become wider. After that, when you remove the group from the GroupPanel, the group indicator is hidden but this will not affect the RadGridView's width any more. What we can suggest you is to set a fixed width for your grid (setting the MaxWidth is the other option), then you can set Width="*" for some of your columns. In this way you will get the desired behavior.
