Vista - inherit controls in WPF

Hi,
I have a dialog with 2 TextBox controls.
I want to add some functionality to one of the them.
I created a class MyTextBox which inherits from TextBox.
How can I connect one of the TextBox controls to my new class ?

I tried to replace the line (created automatically) in "Window1.g.cs":
internal System.Windows.Controls.TextBox YoavTextBox;

with:
internal MyTextBox YoavTextBox;

but I get compilation errors.

Yoav.

Hi,

overwritten every time you build.

If you have:

namespace HelloWorld
{
public class MyTextBox : TextBox
{
// ...
}
}


Then in your XAML code:

<hello:MyTextBox Text="Hello world"
xmlns:hello="clr-namespace:HelloWorld"/>


You can also define the xmlns:hello part in the Window if you prefer.
