 private void RadRibbonView_SelectionChanged(object sender, RadSelectionChangedEventArgs e) { var ribbon = (sender as RadRibbonView); if (ribbon.SelectedItem is RadRibbonTab) { //DO STUFF } else if (ribbon.SelectedItem is RadRibbonBackstage) { //DO OTHER STUFF }

If I click on the backstage, this always triggers as a tab....which is causing me many problems.

Keep backstage open after an event within it ?

Hi,

We have an option to close our app in our Backstage panel:

var result = MessageBox.Show(unsavedChangesMsg, Properties.Resources.MessageBoxTitle_Confirmation, MessageBoxButton.OKCancel, MessageBoxImage.Question);

...if the user selected "Cancel" then the ribbon goes to last tab selected instead of staying in the backstage. The backstage isn't considered to be a tab it seems, so keeping it open is problematic it seems.

I've tried:

- Hiding all tabs.

- Unselecting all tabs.

- MasterRadRibbonView.SelectedIndex = -1;

- MasterRadRibbonView.SelectedItem = MasterRadRibbonView.Backstage;

- IsBackstageOpen = true; //databinding

...and a few other things, but when the screen comes back after the user exits out of the pop-up window, the last tab is loaded, when we want it to stay on the Backstage until the user selects a tab themselves.

RibbonTab IsSelected issue in RibbonView

Hi,

I have a RadRibbonView with RadRibbonTab inside it to display Module names.
The itemsource of RadRibbonView is set with my modules and these modules are converted to tabs at runtime using a converter to the ItemSource.
From the converter, I set the first tab as IsSelected= true and it set correctly and higlights the specific tab.
But the details/contents of that tab is not displayed.
Ie: OnSelectionTabChanged event doesn't fire in this case.
Where when I click a different tab, it works fine. but when i click the first tab again, it doesn't work.
When I checked using WPF inspector, i can see that IsSelected property of the first tab is always true even when i select a different tab.
any help?

am using 2013 Q1.
The same code was working perfectly whern i used rabribbontab. Now am converting this to radribbonview ince ribbontab doesnt exists in the new release.

Cheers

No item shown when SelectionBoxesVisibility is set to Collapsed

Hello,

what is the purpose of setting the SelectionBoxesVisibility property to Collapsed ? When I do this, the MultiClumnComboBox does not show any value, as if no item is selected.

Close button in one RadTabItem

I want to ad a close button to 1 out of 2 RadTabItems. The documentation ads the button to all RadTabItems. How can I do this?
My xaml code is as follows (and I want the close button on the second RadTabItem, never the first one):

    
            <telerik:RadTabControl> 
        
            <telerik:RadTabItem Header="{Binding ElementName=operationContentControl, Path=Content.DataContext.Header}" IsSelected="{Binding IsOperationSelected, Mode=TwoWay}"> 
        
            <ContentControl x:Name="operationContentControl" cal:RegionManager.RegionName="{x:Static infrastructure:RegionNames.MainRegion}" /></telerik:RadTabItem> 
        
            <telerik:RadTabItem Header="{Binding ElementName=protocolContentControl, Path=Content.DataContext.Header}" IsSelected="{Binding IsProtocolSelected, Mode=TwoWay}" Visibility="{Binding IsProtocolVisible, Converter={StaticResource boolToVisibilityConverter}}"> 
        
            <ContentControl x:Name="protocolContentControl" cal:RegionManager.RegionName="{x:Static infrastructure:RegionNames.ProtocolRegion}" /><telerik:RadTabItem> 
        
            </telerik:RadTabControl>

Regards,
Roy

07. Height="Auto"

08. Margin="0"

09. DocumentInheritsDefaultStyleSettings="True"/>

Vertically Merged Cells in a CheckBox Column

Hi,

I have a project in which I am trying to support merged cells for all columns. I notice however that a CheckBox Column doesn't fully support this feature inasmuch as a GridView always displays the values True or False in text form across merged cells (or in my case "1" or "0").

I thought this was an oversight by me but I noticed it in the documentation here where the IsMarried column is shown.

Is this the intended design or does Telerik plan to change this? Personally I would prefer the merged cell also to display a CheckBox.

Many thanks.
