Please explain the following page initialization mechanism

wanderwb

There are two pages, a.aspx and b.aspx. There is an Image control on the page (ID value: b). In the background Page_Load () delegate event code of a page, there is such a sentence: b.ImageUrl = "xyz.jpg";
I do not know why after each execution of this statement, it will automatically go to the Page_Load () event code of page b. Please master to explain, thank you!

By the way, there is no asp control in the foreground of page b, only the background code.

Add this.b.ImageUrl should be fine
