Exception thrown when pinning a pane after unpinning it when one Pane Visibility is Collapsed

[Rick Glos]

Hello,

I have created a simple WPF app to demonstrate a bug we are seeing.

In our application, we have a RadPane that only certain users should be able to see because of Permissions.  We are attempting to do this using the Visibility property on the RadPane.

If I create a RadDocking control with a RadPaneGroup and set one of the RadPane elements Visibility property to Collapsed.  It does two things.

1. It shows up when I unpin the Visible RadPane (note that if you unpin the Service Card Explorer, you suddenly see the Operations Explorer)
2. If you try and repin the Pane, a Cannot call Arrange on a UIElement with infinite size or NaN. exception is thrown.

XAML

<Window x:Class="RadDockingPaneVisibilityBug.MainWindow"

        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <telerik:RadDocking Grid.Row="1">
            <telerik:RadDocking.DocumentHost>
                <telerik:RadSplitContainer>
                    <telerik:RadPaneGroup>
                        <telerik:RadDocumentPane Header="Content" Visibility="Collapsed" CanUserClose="False">
                            <TextBlock Text="Content" />
                        </telerik:RadDocumentPane>
                    </telerik:RadPaneGroup>
                </telerik:RadSplitContainer>
            </telerik:RadDocking.DocumentHost>
            <telerik:RadSplitContainer>
                <telerik:RadPaneGroup>
                    <telerik:RadPane Header="Service Card Explorer" CanUserClose="False">
                        <TextBlock Text="Service Card Explorer" />
                    </telerik:RadPane>
                    <telerik:RadPane Header="Operations Explorer" CanUserClose="False" Visibility="Collapsed">
                        <TextBlock Text="Operations Explorer" />
                    </telerik:RadPane>
                </telerik:RadPaneGroup>
            </telerik:RadSplitContainer>
        </telerik:RadDocking>
    </Grid>
</Window>

Steps to reproduce:

1. Launch the application
2. Unpin the 'Service Card Explorer' pane - note we suddenly see the Operations Explorer pane - this should not be
3. Unpin the 'Operations Explorer' pane
4. Try and pin the 'Service Card Explorer' pane - note the exception

Hello,

The Visibility property of the RadPane works only for the tabbish visual in the RadPaneGroup. It is not supposed to set the content to hidden also.

For your scenario please use the IsHidden property of the RadPane and set it to False instead of setting the Visibility to Collapsed.

Thanks that fixed it.
