Question

I have a TabControl where the TabItems are DataTemplated. The template seems to work correctly, in that the usercontrol I want to show in the TabItem is showing correctly.

What I am not sure of is how to get a “x” to show up in the TabItem so I can close each tab, since they are dynamically generated through a template.

Being fairly new to WPF, I am starting to pick up on many of the concepts, but the TabControl gave me a lot of trouble, so I may very well have the template workable, but not maintainable.

This is what I have, and I would like to be able to close each TabControl. I will also need to be able to fire a custom event when that TabControl is closed.

<UserControl x:Class="Russound.Windows.UI.UserControls.CallLog.CaseReaderWpf"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:CallLog="clr-namespace:Russound.Windows.UI.UserControls.CallLog"
    Height="637" Width="505">

    <UserControl.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/Russound.Windows;component/UI/RussoundDictionary.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </UserControl.Resources>

    <TabControl x:Name="tabCases" >
        <TabControl.ItemTemplate>
            <DataTemplate DataType="{x:Type TabItem}">
                <StackPanel>
                    <TextBlock Text="{Binding Path=Id}" />
                </StackPanel>
            </DataTemplate>
        </TabControl.ItemTemplate>
        <TabControl.ContentTemplate>
            <DataTemplate DataType="{x:Type TabItem}">
                <CallLog:CaseReadOnlyDisplay DataContext="{Binding}" />
            </DataTemplate>
        </TabControl.ContentTemplate>
    </TabControl>
</UserControl>
