Hidden field's value gets lost

Hidden fields loose their value on postback, when the container they are placed in, is disabled. However, when they get disabled, their value is kept.

Make a page refresh after a form submit

Guess what happens, if you insert new records in a datatable on a button click, then press F5, or the refresh button of the browser?! The same record is going to be inserted again. I found this very annoying.

A simple solution: redirect to the same page at the end of the button click event handler.

private void SaveClicked(object sender, EventArgs e)

{

// insert a record somewhere in a datatable

Response.Redirect(itself); // itself being the URL of the current page

}
