WPF Visibility of a UI element based on combo selection

Question

Trying to show a label only when a certain item in a combo is selected. Code should pretty much explain it.

Answer 1

There are two issues here. First the default visibility should be specified in the style. But even with that it won't work because the binding on the trigger is comparing a SelectedValue, a ComboBoxItem object with a string object and that will never be equivalent. To keep the example simple, I've placed appropriate values in the ComboBoxItem's Tag properties. Although the actual implementation of the comparison will likely vary based on the specific needs of the app.

    
        Don't show the label
        Show the label
    

    This is my label
