radpane and document host issue

[Manoj]

I am planning to use this behavior...

<Grid  >
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="4*"/>
                    <ColumnDefinition Width="4"/>
                    <ColumnDefinition Width="1*"/>
                </Grid.ColumnDefinitions>
                
                <Grid Grid.Column="0">
                    <Controls....../>
                </Grid>

                <GridSplitter Grid.Column="1"/>
                
                <Grid Grid.Column="2" >
                    <Controls: CustomControl/>
                </Grid>
            </Grid>


this custom control in the third column is a rad docking control as shown below:

<telerikDocking:RadDocking x:Name="dockPane" HasDocumentHost="False"> 
                <telerikDocking:RadSplitContainer InitialPosition="DockedRight" Orientation="Vertical" >
                    <telerikDocking:RadPaneGroup Background="White" >
                        <telerikDocking:RadPane  IsPinned="True" CanUserClose="True">

                            <telerik:RadGridView AutoGenerateColumns="False" ShowGroupPanel="False">
                                <telerik:RadGridView.Columns>
                                    <telerik:GridViewDataColumn>
..........
                                    </telerik:GridViewDataColumn>
                                    <telerik:GridViewDataColumn>
..........                                        
                                    </telerik:GridViewDataColumn>
                                </telerik:RadGridView.Columns>
                            </telerik:RadGridView>
                        </telerikDocking:RadPane>
                    </telerikDocking:RadPaneGroup>
                </telerikDocking:RadSplitContainer>            
        </telerikDocking:RadDocking>


Issues i am facing are as follows:
1) After unpinning, on mouse over of unpinned tab, exception is coming (cant not set the property width to -28.4)
2) If you do a unpin, document host is not getting collapse, it is visible, only the rad pane is tabbed on the right hand side but document host background is still visible even though i am setting the document host to false as part of docking control
3) If i want to add a rectangle at the top of the rad docking control , is it possible?

Hello Manoj,

Straight to your questions:

1. I couldn't reproduce the issue, could you please provide us with more detailed information?
2. When you unpin the Pane it reveals the background of the Docking control and this is its correct behavior.
3. Please provide more information on how exactly you need to place the rectangle.

I'm looking forward to your response.

HI Kalin,

Please find the screen shot attached.

In the Pinned.JPG, everything is fine, document host is collapsed (behavior is fine until you resize the pane with the help of a grid splitter).

In the backgroundIssue.JPG, i unpinned the rad pane after some resizing and because of that background color of the document host is visible and it is not collapsed properly.


The other issue is:
After unpinning (isPinned = false), then on mouse over of unpinned tab, exception is coming (-28.4 is not a valid value for property width) but i am not setting the width anywhere in my xaml. This is the exception's stack trace

Hello,

We noticed that you have opened another thread with ID: 698114 about the same issue and we responded to you in the other post. Could we continue the discussion there?

I'll post our response here too, so that it is available to the community:

We are unaware of issues with pinned/unpinned Panes and the DocumentHost of the Docking control. As I can see on the attached screenshots it looks like you have made some customizations which could be causing the issue.

yes, we will continue the discussion as part of the thread 698114.
