Showing and hiding RadPanes conditionally

[Erwin]

Hi,

I have two radpanes in one radpanegroup, each with a chart. I want to show one of these two (and only one), based upon some conditions.
I have made a  property for Visibility and two  'Boolean' properties, one holding true or false and the other holding false or true.
With these properties I set the radpane properties like Visibility, IsHidden, IsEnabled, IsSelected for both radpanes.
However, this does not toggle shown radpanes / charts. (actually, it does, but I have to click on the radpane tab to get it shown....)
I've tries a lot of different combinations, but I haven't succeeded so far.

Can anybody tell me how to do this?

This is how the two radpanes in XAML look like:

                    <telerik:RadPaneGroup x:Name="graph1RadPaneGroup">                 
                        <telerik:RadPane x:Name="multiOrderLineRadPane" 
                                         Header="[Problem Orders By Supplier]" 
                                         Visibility="{Binding OrderCountBySupplierGraphVisibility}" 
                                         IsPinned="True"
                                         IsSelected="{Binding  IsMultiOrderItemsSelected}" 
                                         IsEnabled="{Binding IsMultiOrderItemsSelected}" 
                                         CanUserClose="False">
                            <views:OrderCountBySupplierGraphView/>
                        </telerik:RadPane>
                        <telerik:RadPane x:Name="singleOrderLineRadPane"  
                                         Header="[Graph 1a]" 
                                         Visibility="{Binding SingleItemOrderCountGraphVisibility}"                                          
                                         IsPinned="True"                                       
                                         IsSelected="{Binding IsSingleOrderItemSelected}" 
                                         IsEnabled="{Binding IsSingleOrderItemSelected}" 
                                         CanUserClose="False">
                            <views:SingleItemOrderCountGraphView/>
                        </telerik:RadPane>
                    </telerik:RadPaneGroup>

Looking forward to replies,

Both Panes in the RadPaneGroup have the IsSelected property binded to boolean values, which are always opposed (true & false or false&true).
When the binded properties change, the panes do switch, but the pane content of the prior pane is still visible (so header and 'tab' do change).
Also, the SelectionChanged event on the RadPaneGroup does not fire.
How do I get the RadpaneGroup.SelectionChanged event fired?

Hello Erwin,

 
Thank you for contacting us.

If I understand your scenario correctly, you want to show the content only for the active pane (active means selected and focused). Please, correct me if I am wrong. With the current Q2 release we introduced the RadDocking.ActivePane, RadPane.IsActive properties and the RadDocking.ActivePaneChanged event. Using these properties and event, you could easily get the current pane, show the content only for this pane and hide content of the others.


Hope this helps. Please do not hesitate to contact us if you require any further information.

All the best,

Thank you for reply. For the visiblity, isselected I have made properties in the viewmodel, and the two panes bind to them.

The properties you mention on radDocking level work fine; I can see them change to the correct values when I select a pane by mouse.
However, when my Isslected and Visiblity properties change, the radDocking_ActivePaneChanged event does not fire, I think because I have to put Focus on the selected Pane. I don't know how to do it from the code behind.

Is it possible to get a small sample for this?

Thanks in advance,

Erwin

Hi Erwin,

 
If order to set ActivePane for the RadDocking control, I would suggest using the RadDocking.ActivePane property. Anyway, if you want to activate it using Focus, please make sure this pane is selected and then focus it, using the Focus() method. Also, I would suggest using the RadPane.IsHidden property instead of Visibility, because the RadPane is only the small tab item in the RadPaneGroup and the content of the pane if placed in the RadPaneGroup, not in the pane and if you set it hidden, it will hide its content as well.

Hope this helps.
