RadPane.Title issue

[Manuel Felício]

Hello,

RadPane.Title is a string property but there is a RadPane.TitleTemplate. Why not make the Title an object property instead of a string property and treat it like Header/HeaderTemplate ? In this case we'll be able to declare a datatemplate for Title with bindings.

Anyway, my goal was to have a datatemplate for TitleTemplate that had a ContentPresenter for the Title string and some buttons bound to commands that I had declared in a viewmodel class that would be bound to the Title Property (I can't do this because it's a string!).

Best regards,

MF.

Hello Manuel,

The main reason why we keep it string and not an object is because it is not expected to be a visual element and if we use object we cannot stop the user to put a visual element in it. On the other hand it cannot be a visual element, because it might be displayed in more than one places. 

We will think about a way to enable your scenario, but unfortunately this will not happen earlier than Q1 2010 as this will be a breaking change.

Thanks for your reply Miroslav.

I don't think it would be a breaking change since you can set String value into an Object property with no compile errors. Existing projects won't stop working. You could use a default template with a TextBlock for the Title when it is a String value and when it is some random object just let the user specify the data template.

Anyway, why can't it be a visual element? If you can specify a datatemplate for it you can make the Title be anything.

Best regards,

MF.

Hi Manuel,

Yes, you are right - you will be able to set string to object, but if some is setting the Title to some variable of type string this will stop compiling.

You are right for the DataTemplate as well but this is not what I wanted to say - it won't be allowed to set a visual element to the Title property directly (the title is displayed in more than one place).

Hi,

You are right, setting the title to a variable of type string would cause a compile error. I didn't think of that, sorry.

I guess I'll have to dig deeper in control templates to accomplish what I'm trying to do.

Thanks,

MF.

Hi,

   I was looking for this as well. I still don't see the Title as Object instead of 'String" as of 10/6/2010.
   Can you suggest a workaround to bind my buttons and menus which are on the template ?


Thanks

Hi Srinu,

As there is no good work-around for this problem we are planning to change the type of the Title property.

Hello,

Just in case anyone wants a workaround, I found a way to add buttons to the TitleTemplate that are bound to your viewmodel. This is how you do it:

<telerik:RadDocking>
      <telerik:RadSplitContainer Width="800" telerik:StyleManager.Theme="Metro" Orientation="Horizontal" InitialPosition="DockedRight" telerik:ProportionalStackPanel.RelativeSize="100, 100">
                            <telerik:RadPaneGroup telerik:StyleManager.Theme="Metro">
                                <telerik:RadPane CanUserClose="False" CanUserPin="True" ContextMenuTemplate="{x:Null}" Header="{Binding SelectedCase}">
                                    <telerik:RadPane.TitleTemplate>
                                        <DataTemplate>
                                            <StackPanel Orientation="Horizontal" Visibility="{Binding Converter={StaticResource NullVisibilityConverter}}">
                                                <HyperlinkButton Foreground="White" Content="{Binding CustomerName}" NavigateUri="{Binding AccountUrl}" />
                                                <TextBlock Text=" - " />
                                                <Button Content="hello" Command="{Binding Test}" />
                                            </StackPanel>
                                        </DataTemplate>
                                    </telerik:RadPane.TitleTemplate>
                                    <Grid Background="White" Visibility="{Binding SelectedCase, Converter={StaticResource NullVisibilityConverter}, Mode=TwoWay}">
                                        <View:TileContentLarge DataContext="{Binding SelectedCase}"/>
                                    </Grid>
                                </telerik:RadPane>
                            </telerik:RadPaneGroup>
                        </telerik:RadSplitContainer>
                    </telerik:RadDocking>

What you do is you have your Header in your RadPane bind to your ViewModel, and then you create a TitleTemplate that has buttons, and bind to the commands/properties in your view model. When I click on the button in my TitleTemplate, I am able to access the command in my ViewModel.

Just wanted to post this just in case anyone comes across this thread.

Hello Bryce,

Thank you for sharing your code. This wasn't possible before changing the type of the Title property from String to object and currently this is the recommended way to achieve this.
