Hi Infragistics,

When using Collapsed-Variant in a RibbonGroup and the RibbonGroup gets larger, the Ribbgroup will be collapsed (if there is not enough space to show the RibbonGroup content). If the RibbonGroup is collapsed you can view the RibbonGroup content by clicking the DropDownButton. A Popup will apear, where you can see the original RibbonGroup content. If you then make the RibbonGroup content smaller I would expect, that the RibbonGroup would restore the original expanded state (without DropDown), but this is not the case. Only if you enlarge the window width the RibbonGroup will restore to its original visual state. Will this be fixed or is there a work around?

I added an example where you can play around with. Just resize the TextBoxes by entering or removing some letters.

                <ribbon:RibbonGroup Id="Group1" Caption="Group1">
                    <TextBox MinWidth="100"/>
                </ribbon:RibbonGroup>
                <ribbon:RibbonGroup Id="Group2" Caption="Group2">
                    <TextBox MinWidth="100" Text="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"/>
                </ribbon:RibbonGroup>
            </ribbon:RibbonTabItem>
        </ribbon:XamRibbon.Tabs>
    </ribbon:XamRibbon>
