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>

[Solved] 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.

Duplicate row group key

I'm having an issue where I sometimes get two groups with a key of empty string when I add a grouping to my data.

It's really important that these group keys be unique because I'm doing some fairly complicated grid navigation in hierarchical grids and I rely on that key being unique so I can programatically make decisions about where to move focus.

Is there a grouping maximum or something that I'm missing, or is this a Telerik bug?

Set the AutoCompleteMode in a style generates an error in my XAML

Hi,

I have following style applied for all my RadMultiColumnComboBox controls (in the app.xaml):

<Style x:Key="DefaultTelerikRadMultiColumnComboBoxStyle" TargetType="telerik:RadMultiColumnComboBox" BasedOn="{StaticResource RadMultiColumnComboBoxStyle}">

<Setter Property="AutoCompleteMode" Value="Search"/>

<Setter Property="FontFamily" Value="{StaticResource DefaultFont}"/>

<Setter Property="FontSize" Value="{StaticResource DefaultFontSize}"/>

<Setter Property="FontWeight" Value="{StaticResource DefaultFontWeight}"/>

<Setter Property="MinHeight" Value="{StaticResource DefaultMinimumHeight}"/>

<Setter Property="KeepDropDownOpen" Value="False"/>

<Setter Property="CloseDropDownAfterSelectionInput" Value="True"/>

<Setter Property="SelectionBoxesVisibility" Value="Visible"/>

<Setter Property="Validation.ErrorTemplate" Value="{StaticResource ErrorTemplate}"/>

<Style.Triggers>

<Trigger Property="IsEnabled" Value="True">

<Setter Property="Background" Value="{StaticResource DefaultTextBoxBackgroundColor}"/>

</Trigger>

<Trigger Property="IsEnabled" Value="False">

<Setter Property="Background" Value="Red"/>

</Trigger>

<Trigger Property="IsFocused" Value="True">

<Setter Property="Background" Value="{StaticResource DefaultTextBoxIsFocusedBackgroundColor}"/>

</Trigger>

</Style.Triggers>

</Style>

<Style TargetType="{x:Type telerik:RadMultiColumnComboBox}" BasedOn="{StaticResource DefaultTelerikRadMultiColumnComboBoxStyle}"/>

With this style applied, I get this error in my XAML files (see attached file): The element "[RadMultiColumnComboBox]" could not be displayed because of a problem with System.Windows.StaticResourceExtension: CollectionView must have value. Parameter name: collectionView.

The error is provoced by the setter of the AutoCompleteMode. The error disappears when this setter is deleted.

Setting the AutoCompleteMode directly on a RadMultiColumnComboBox (with the style applied) does not cause any problems.

Any ideas ??

Hans
