WPF click event handler get textblock text

Question

I have a text block in my xaml: ``` ``` On the code behind I have an event handler for click (double-click) ``` private void interface_mouseDown(object sender, MouseButtonEventArgs e) { var tb = sender as TextBox; if (e.ClickCount == 2) MessageBox.Show("Yeah interfac " + tb.Text); } ``` I'm getting a NullReferenceException.

Accepted Answer

```
var tb = sender as TextBox
```

This results in `null` because it's actually a `TextBlock`.

Just change to

```
var tb = sender as TextBlock
```
