Click Event Sender in wpf

Question

I am desinging a wpf application. I code a grid(which has 35 textblocks)-wide context menu. when I click mouse's right button I need to learn on which textblock I clicked. But click event gives centext menu as a sender. How can I reach on which textblock the user click right mouse button?

My XAML code---------------------------------------------------------------:

<Grid>
        <Grid.ContextMenu>
            <ContextMenu>
                <MenuItem Header="Hafta İçi" x:Name="btnWeekDay" Click="btnWeekDay_Click" />
                <MenuItem Header="Cuma" x:Name="btnFriday" Click="btnFriday_Click"/>
                <MenuItem Header="Cumartesi" x:Name="btnSaturday" Click="btnSaturday_Click"/>
                <MenuItem Header="Pazar" x:Name="btnSunday" Click="btnSunday_Click"/>
                <MenuItem Header="İdari İzin" x:Name="btnAdminLeave" Click="btnAdminLeave_Click"/>
                <MenuItem Header="Bayram/Tatil" x:Name="btnHoliday" Click="btnHoliday_Click" a/>
            </ContextMenu>
        </Grid.ContextMenu>

My C# code-------------:

private void btnWeekDay_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show(sender + e.Source.ToString());
        }

Did you check the MouseButtonEventArgs' OriginalSource property? — Clemens
My event is mouse right button click so I can't reach mousebuttoneventargs. — BilginAksoy
The code you posted is showing you handling Click, not MouseRightButtonDown. There is also no TextBlock to be seen anywhere in your code. Please provide a good minimal reproducible example that reliably reproduces the issue. Note that with the ContextMenu attached to the Grid, it's the Grid handling the mouse event that opens the context menu. You might want to consider styling your grid items so that each of them actually owns a context menu. — Peter Duniho

I found the answer. 1. I moved contextmenu from grid to the textblocks. 2. I fired contextmenuopening event and catch the texblock on which I click rght mouse button.

Here is the xaml code.

    <Page.Resources>
        <Style x:Key="txtBlockStyle" TargetType="{x:Type TextBlock}">
            <Setter Property="TextBlock.Background" Value="AliceBlue"/>
        </Style>
        <Style x:Key="borderStyle" TargetType="{x:Type Border}">
            <Setter Property="BorderThickness" Value="1"/>
            <Setter Property="BorderBrush" Value="DarkGreen"/>
        </Style>
        <ContextMenu x:Key="txtBlockContextMenu">
            <MenuItem Header="Hafta İçi" x:Name="btnWeekDay" Click="btnWeekDay_Click" />
            <MenuItem Header="Cuma" x:Name="btnFriday" Click="btnFriday_Click"/>
            <MenuItem Header="Cumartesi" x:Name="btnSaturday" Click="btnSaturday_Click"/>
            <MenuItem Header="Pazar" x:Name="btnSunday" Click="btnSunday_Click"/>
            <MenuItem Header="İdari İzin" x:Name="btnAdminLeave" Click="btnAdminLeave_Click"/>
            <MenuItem Header="Bayram/Tatil" x:Name="btnHoliday" Click="btnHoliday_Click" />
        </ContextMenu>
    </Page.Resources>
.....
    <Border Style="{StaticResource borderStyle}" Grid.Column="0" Grid.Row="1" >
                <TextBlock x:Name="txtDate1"  ContextMenuOpening="CustomContextMenuOpening" ContextMenu="{StaticResource ResourceKey=txtBlockContextMenu}"></TextBlock>
            </Border>

Here is code behind.

TextBlock targetTextBlock;

private void CustomContextMenuOpening(object sender, ContextMenuEventArgs e)
        {
            targetTextBlock = (TextBlock)sender;
        }
