I am trying to have two tabs [A,B] that contain a sliding tab [A1, B1] and a main tab with content [A2, B2] each.


    <c1:C1DockControl>
        <c1:C1DockTabControl >
            <c1:C1DockTabItem Header="A" >
                <c1:C1DockTabControl DockMode="Docked">
                    <c1:C1DockTabControl DockMode="Sliding">
                        <c1:C1DockTabItem  Header="A1">
                            <TextBlock Text="A1" />
                        </c1:C1DockTabItem>
                    </c1:C1DockTabControl>
                    <c1:C1DockTabControl DockMode="Docked">
                        <c1:C1DockTabItem  Header="A2">
                            <TextBlock Text="A2" />
                        </c1:C1DockTabItem>
                    </c1:C1DockTabControl>
                </c1:C1DockTabControl>
            </c1:C1DockTabItem>
            <c1:C1DockTabItem Header="B" >
                <c1:C1DockTabControl DockMode="Docked">
                    <c1:C1DockTabControl DockMode="Sliding">
                        <c1:C1DockTabItem  Header="B1">
                            <TextBlock Text="B1" />
                        </c1:C1DockTabItem>
                    </c1:C1DockTabControl>
                    <c1:C1DockTabControl DockMode="Docked">
                        <c1:C1DockTabItem  Header="B2">
                            <TextBlock Text="B2" />
                        </c1:C1DockTabItem>
                    </c1:C1DockTabControl>
                </c1:C1DockTabControl>
            </c1:C1DockTabItem>
        </c1:C1DockTabControl>
    </c1:C1DockControl>

A and B are mutually exclusive, as I want the users to be able to flip between their content and see A [A1 slide, A2 dock] or B [B1 slide, B2 dock].

Every time I load this structure though the component breaks with this error:

Any idea on how to fix this or how can I achieve the requirements?

Thank you

Hi,

As I understand, you want to operate with C1DockControl in a way that at any point in time, there is only one pair of sliding and docked tab (A1 & A2 or B1 and B2).

If so, you would need to use code-behind as well. For reference, I have attached an application wherein as you select a sliding tab, only the corresponding docked tab remains visible.

You can modify the application as per your requirement.

Thanks,

Thanks a lot, your example put me on the right track to conclude with a more MVVM approach, see the following:


        <c1:C1DockControl>
            <c1:C1DockGroup>
                <c1:C1DockTabControl x:Name="slidingTab" DockMode="Sliding">
                    <c1:C1DockTabItem x:Name="itemA1" Header="A1" IsSelected="{Binding Model.IsATabVisible, Mode=TwoWay}">
                        <TextBlock Text="A1" Background="DarkGray"/>
                    </c1:C1DockTabItem>
                    <c1:C1DockTabItem x:Name="itemB1" Header="B1" IsSelected="{Binding Model.IsBTabVisible, Mode=TwoWay}">
                        <TextBlock Text="B1" Background="Turquoise"/>
                    </c1:C1DockTabItem>
                </c1:C1DockTabControl>
                <c1:C1DockTabControl x:Name="dockedTab" DockMode="Docked" TabStripPlacement="Top" CanUserSlide="False" CanUserFloat="False" CanUserHide="False" ShowHeader="False" CanUserDock="False">
                    <c1:C1DockTabItem Header="A2" Visibility="{Binding Model.IsATabVisible, Converter={StaticResource BooleanToVisibilityConverter}}">
                        <TextBlock Text="A2" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" TextAlignment="Center" Background="DarkGray"/>
                    </c1:C1DockTabItem>
                    <c1:C1DockTabItem Header="B2" Visibility="{Binding Model.IsBTabVisible, Converter={StaticResource BooleanToVisibilityConverter}}">
                        <TextBlock Text="B2" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" TextAlignment="Center" Background="Turquoise"/>
                    </c1:C1DockTabItem>
                </c1:C1DockTabControl>
            </c1:C1DockGroup>
        </c1:C1DockControl>
