Right-click on a Listbox in a Silverlight 4 app

Question

I am trying to implement what I used to take for granted in Winforms applications. I am a Silverlight noob, so hopefully all this is elementary.

I have a listbox in

Answer 1

I've been looking around for the same thing. I checked the Silverlight Control Toolkit at CodePlex and went through the samples (it's a very handy resource) and here's what I found to be the solution to what you asked:

1. Create an ItemTemplate for your ListBox

2. in the part that you want to be "right-clickable" of your ItemTemplate set the attached property ContextMenuService.ContextMenu that exists within the System.Windows.Controls.Input.Toolkit namespace

3. add MenuItem controls to your ContextMenu and set the Click property to the corresponding click event handler

4. in the event handler, get the DataContext from the sender (you can use that to find the corresponding element in the ListBox)

5. to make that element Selected, just set the SelectedItem property in the list box to it

6. Add any custom logic to the event handler

There's an example in the samples page, just go to "Input->ContextMenu" from the navigation pane.

If you want something concise, Here's a simplified example:

with:

xmlns:controlsInputToolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit"

for the code:

private void show_Click(object sender, RoutedEventArgs e)
    {
        var person = ((MenuItem)sender).DataContext as Person;
        if (null == person) return;
        MessageBox.Show("My Name is: " + person.Name);
        myListBox.SelectedItem = person;
    }

I hope this helps :)
