Hook up right click events to all textbox in silverlight

Question

Is there anyway to add right click events to all textbox controls in silverlight without needing to manually adding it to each control in the whole project?

doing like:

<TextBox x:Name="txtName" MouseRightButtonUp="txtName_MouseRightButtonUp" 
    MouseRightButtonDown="txtName_MouseRightButtonDown" /></TextBox>

then fixing the events in the .cs for about 50+ (hopefully it's just 50+) textboxes can take a while.

If not then what might be the easiest way to do this?

My answer to this question is also the answer to your question.

In short it's probably easiest to derive a type from TextBox, put your MouseRightButtonDown event handler in there and replace all existing instances of textBox with your type.

You can extend your textbox

class SimpleTextBox
{
    public SimpleTextBox()
    {
        DefaultStyleKey = typeof (SimpleCombo);
        MouseRightButtonDown += OnMouseRightButtonDown;
    }

    private void OnMouseRightButtonDown(object sender, MouseButtonEventArgs   
mouseButtonEventArgs)
    {
        //TODO something
    }
}

==========

And use this control. Or as alternative solution - you can create behavior:

CS: ... using System.Windows.Interactivity;

public class TextBoxBehavior : Behavior<TextBox>
{
    protected override void OnAttached()
    {
        base.OnAttached();
        AssociatedObject.MouseRightButtonDown += AssociatedObject_MouseRightButtonDown;
    }

    protected override void  OnDetaching()
    {
         base.OnDetaching();
         AssociatedObject.MouseRightButtonDown -= AssociatedObject_MouseRightButtonDown;         
    }

    private void OnMouseRightButtonDown(object sender, MouseButtonEventArgs mouseButtonEventArgs)
    {
        e.Handled = true;
        // DO SOMETHING
    }
}

XAML:

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

<TextBox ...>
    <i:Interaction.Behaviors>
        <local:TextBoxBehavior />
    </i:Interaction.Behaviors>
</TextBox>

And attach this handler to your TextBox general style.

Doesn't work until I added the tags to specify the behavior. Looks like I'll have to do that one manually. I was thinking of some way so that other coders wouldn't need to do add those. — Bahamut, Feb 19 '13 at 07:42
ok i jest. i updated the post and added the link to a post describing how to add behaviors to styles. — Bahamut, Feb 19 '13 at 10:29
while the poster still hasn't accepted my edits. update: see http://stackoverflow.com/questions/13498216/attach-behaviour-to-all-textboxes-in-silverlight you may ignore the xaml code and proceed to using styles instead — Bahamut, Feb 19 '13 at 12:15
Yes, I meant that you should attach behavior in style, but had mistake and wrote "handler" instead of "behavior" :). Thanks for updating. — Roman Badiornyi, Feb 19 '13 at 14:21
