WPF listbox. Skip underscore symbols in strings

Question

I have some WPF ListBox which is dynamically populating with items. Something like this :

ListBox.Items.Add
(new ListBoxItem { Content = new CheckBox { IsChe         


        

Answer 1

The default template for the CheckBox contains a ContentPresenter whose RecognizesAccessKey is set to true. If the content is a string (which it is in your case), then the ContentPresenter creates an AccessText element to display the text. That element hides the underscore until the Alt key is pressed because it will treat it as a mnemonic. You can either retemplate the CheckBox such that its ContentPresenter's RecognizesAccessKey is false or better yet just provide a DataTemplate as the ContentTemplate which contains a TextBlock. If you're not sure if the content will be a string then you can set the ContentTemplateSelector and in code provide a DataTemplate which contains a TextBlock only if the item is a string. e.g.
