Hi,

       I have custom templated RadTabControl with RadTabItems. The control has fixed width and tab items are all in the same line.
If there is too many tab items the text in tab headers are cut from the right. It can't be seen whole. The only solution for me is to
split tab items into the two lines, but I don't know how. I tried with placing RadTabItems in two horizontal stack panels one beneath the other with no luck. In such situation the RadTabItem content is not shown at all. Could you help me with this issue? 

 

 

<!--Tab Item Top Template--> 
 
<ControlTemplate x:Key="TabItemTopTemplate"

This is the RadTabControl with tabs that should be shown in two lines:

 

<

 

telerik:RadTabControl x:Name="tbcAdvancedSearchFields"

 

 

Style="{StaticResource AdvancedSearchFieldsTabControl}">

 

 

 

 

<!--Debtor fields-->

 

 

 

 

<telerik:RadTabItem x:Name="tbciAdvancedSearchFields"

 

 

Header="{Binding DebtorsFieldsHeaderText}"

 

 

Style="{StaticResource AdvancedSearchFieldsTabItemStyle}">

 

 

 

<custom:AdvancedListBox x:Name="lbFields"

 

 

ItemsSource="{Binding DebtorsFields}"

 

 

SelectedItem="{Binding SelectedField, Mode=TwoWay}"

 

 

DisplayMemberPath="ColumnDef.HeaderName"

 

 

IsItemEnabledPath="IsFieldEnabled" />

 

 

 

 

</telerik:RadTabItem>

 

 

 

<!--Debtor free fields-->

 

 

 

 

<telerik:RadTabItem x:Name="tbciAdvancedSearchUserFields"

 

 

Header="{Binding DebtorsFreeFieldsHeaderText}"

SelectedItem="{Binding SelectedField, Mode=TwoWay}"

 

 

DisplayMemberPath="ColumnDef.HeaderName"

 

 

IsItemEnabledPath="IsFieldEnabled" />

 

 

 

 

</telerik:RadTabItem>

 

 

 

<!--Selections-->

 

 

 

 

<telerik:RadTabItem x:Name="tbciSelections"

 

 

Header="{Binding SelectionsHeaderText}"

 

 

Style="{StaticResource AdvancedSearchFieldsTabItemStyle}">

</telerik:RadTabItem>

 

 

 

 

<!--Grid specific fields-->

 

 

 

 

<telerik:RadTabItem Header="{Binding GridSpecificFieldsHeaderText}"

 

 

Visibility="{Binding IsGridSpecificVisible, Converter={StaticResource VisibilityConverter}}"

 

 

Style="{StaticResource AdvancedSearchFieldsTabItemStyle}">

 

 

 

 

<custom:AdvancedListBox x:Name="lbGridSpecificFields"

Hi Ivan,

 Thank you for your feedback. We have considered this scenario and we will implement it, but for the moment I cannot bind to a specific date. A little trick you can do in this case is, instead of using StackPanel, to use Telerik's WrapPanel(located in Telerik.Windows.Controls.dll), as shown bellow:

<telerikNavigation:RadTabControl x:Name="tabControl1" Width="500" Height="500" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
    <telerikNavigation:RadTabControl.ItemsPanel>
        <ItemsPanelTemplate>
            <telerik:RadWrapPanel />
        </ItemsPanelTemplate>
    </telerikNavigation:RadTabControl.ItemsPanel>
</telerikNavigation:RadTabControl>

The problem is that if you select an item, the selected tab will not go automatically down:

Let me know if this works for you.

Hi Jay,

Currently using a wrap panel will not automatically adjust the row of the selected item as expected.

Unfortunately our TabPanel does not currently support automatic breaking.

Hello James,

Yes, it is already implemented. You can use the OverflowMode property like so:

<telerik:RadTabControl OverflowMode="Wrap">
    <telerik:RadTabItem Header="Tab Item 1" />
    <telerik:RadTabItem Header="Tab Item 2" />
    <telerik:RadTabItem Header="Tab Item 3" />
    <telerik:RadTabItem Header="Tab Item 4" />
    <telerik:RadTabItem Header="Tab Item 5" />
    <telerik:RadTabItem Header="Tab Item 6" />
</telerik:RadTabControl>

Regards,
Miroslav
