Question

I am having trouble with textbox.textchanged event. my textboxes are data-bound and when the page is loaded, textchanged event triggers. How do I prevent it from happening and only trigger when the user makes any sort of changes?

Answer 1

Inside textchanged event handlers you can verify if window (or usercontrol, or whatever) is loaded:

if (this.IsLoaded)
{
   //your logic here
}

This way you can skip the first firing of TextChanged events, when the window is not loaded yet.
