Double calling element event?

Question

ASP.NET

Good afternoon.
There is a page on WebForms, on it is a GridView, inside it are TextBox elements. I create an event handler for the OnTextChanged event for these TextBoxes. And for some reason this handler is always called twice in a row. This also calls Page_Load 2 times.
What could be the problem?

Answer 1

In my case it was a debug glitch. If you put breakpoints, then they stopped twice. If you put logging instead of them, then it will be logged once.
