WPF TabItem Element MouseClick Event

Question

In WPF app inside a TabControl there is a TabItem element with one Label. I want to fire the event on MouseClick on the Tab of this TabControl, but the event MouseLeftButtonDown:

<TabItem Header="Header1" MouseLeftButtonDown="TabItem_MouseLeftButtonDown" >
      <Label Height="28" Name="AdderLbl" Width="120" Background="Azure" >Label</Label>
</TabItem>

fires only on click over the label. It is not wat I want.

How I could fire the event on MouseClick over the Tab, not its content?

Answer 1

What are you trying to achieve? It looks like you're trying to trap when the user moves to the tab, if so you can hook a different event SelectionChanged

:-)

Answer 2

I did not want selectionchanged event because that would involve a switch. So i wanted an event directly on the tab clicked.

While i thought an MouseDown event was what I was looking for.... after wiring up all sorts of mouse events with break points; i found the MouseUp events worked for me.

So I used MouseLeftButtonUp or MouseUp.

Answer 3

For who really want to use something like MouseLeftButtonDown event, you can use the "MouseUp" event instead. =)

Answer 4

While handling SelectionChanged event is the better approach to handling tab changes, here is a possible solution to your question. I don't recommend it in your case, but it illustrates an approach that may be useful in other cases

    <TabControl>
        <TabItem>
            <TabItem.Header>
                <Button Click="Button_Click">
                    <Button.Template>
                        <ControlTemplate>
                            <Label>Header1</Label>
                        </ControlTemplate>
                    </Button.Template>
                </Button>
            </TabItem.Header>

            <Label Height="28" Name="AdderLbl" Width="120" Background="Azure" >Label</Label>
        </TabItem>
    </TabControl>

Answer 5

You need the event Selector.Selected

Answer 6

<TabControl x:Name ="TabControls" Dock="Top" DockWidth="500" DockHeight="500"     TabItemShape="Rounded">
<TabControl>

 TabControls.SelectionChanged += SelectionChanged;

 private void SelectionChanged(object sender, SelectionChangedEventArgs selectionChangedEventArgs) {

     var itemTab = (TabItem) TabControls.SelectedItem;

    (...) 
 }
