• How to Cancel (stop) execution of my page in Page_Load event after a Postback?

Is there any e.Cancel() or stopPostBackOperation() function? If i use Exit Sub, then the control goes to button1_Click... I try

  Thank you very much for your quick responses! Venkatu, you said me to "// end the operation". How can i do that? How to "End" the operation. I don't want to check on every button's handler if isAuthorizedUser(). I want to check only once ! I want a central check only once in PageLoad event. Do you know any possible central-based solution to check only once if isAuthorizedUser()? P.S. I'm reading your article now to see the AJAX solution...

  yes, thank you but i've already know that. I know that i can do that for ex. by using an asp:panel and set visible=true or false, depending on my needs. But i don't want that! I want way/solution to do that by clearing the output. I want something like Response.Clear() or Page.InnerHtml.clear() or something simillar to clear the Test's.aspx code dynamically and returns nothing (blank file)... -OR- I want a way to clear the "ContentPlaceHolder2" that loads that text inside the

• Re: How to define a variable

  Hello khparhami , if i understand well, your proble is that your public values are NULL after you press the first button.
