DataGrid inside TabItem event handling

Question

I have a TabControl with two TabItems, inside the one TabItem I have a DataGrid. I'm trying to handle the TabItem click, and it works, but, when I click in one row of the "dataGrid1" the event "TabItem_MouseLeftButtonUp" of TabItem click is fired too. See the code:

<TabControl Height="211" HorizontalAlignment="Left" Margin="33,29,0,0" Name="tabControl1" VerticalAlignment="Top" Width="417" >
        <TabItem Header="tabItem1" Name="tabItem1">
            <Grid />
        </TabItem>
        <TabItem MouseLeftButtonUp="TabItem_MouseLeftButtonUp">
            <DataGrid AutoGenerateColumns="True" Height="134" Name="dataGrid1" Width="307" />
        </TabItem>
</TabControl>

Note: I can't use the personalize <TabItem.Header> because I'm using MahApps, if I use TabItem.Header the style os TabItem will break.

You will recieve the EventArgs with MouseLeftButtonUp event. Just filter out whatever you need.

The MouseLeftButtonUp event is bubbling routed event. When you on the DataGrids row the event bubbling through its ancestors and calls the corresponding handlers, TabItem_MouseLeftButtonUp for TabItem in your case.

In your TabItem_MouseLeftButtonUp event you can check who raised the event, which control is the origin. If its not the TabItem do nothing.

private void TabItem_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
     if(sender is TabItem)
     {
           //do the work
     }
}

When a click on the TabItem the OriginalSource is a Border, and when i click right on the text of the TabItem the OriginalSource is a TextBlock, so, this solution dont work. – Ewerton Sep 19 '12 at 12:30
I do some modifications in your solution the sender.GetType() will return the type os the control (DataGrid or TabItem), so, your solution works, i will mark it as answer, can you edit it? – Ewerton Sep 19 '12 at 12:40
