Question

I want to run some code when the Window or Control is first displayed. I can’t use Loaded because that can fire more than once. I can’t use Initialized because that is done by the constructor.

Is there an event somewhere between?

Answer 1

Unfortunately there is no such event. You can use a boolean in the Loaded Method to make sure your stuff only fires once –

if(!IsSetUp)
{
   MySetUpFunction();
   IsSetUp = true;
}
