Question

I have a breakpoint in a form’s OnLoaded event (which dynamically creates some controls), yet when I instantiate the form, it simply sits there looking blanched, and Window_Loaded() is never called.

I instantiate the form with a custom constructor:

NoUseForAName nufan = new NoUseForAName(iListMsgTypes, dtFrom, dtTo);
nufan.Show();

And have added the Loaded() event, which I expect to get called directly after I call .Show() on the form:

private void Window_Loaded(object sender, RoutedEventArgs e)

Why is [Window_]Loaded() not getting reached?

Answer 1

You should either add

InitializeComponent();

as the first line of your custom constructor, or call the default constructor like this:

public NoUseForAName(...)
    : this()
{
    ...
}
