I have a master page containing menu items and if i click on any menu item then postback happens(it's not an asynchronous postback) that page loads in the content area. Now, if the page has taken some time to load and the user again clicks some other menu, then at some cases, it is crashing. So what i want to do is when postback is happening, I want to restrict the user to click anywhere on the master page or content page. We have achieved this on asynchronous postback.... But cant find a solution during postback.

I am developing a website. I have created a master page called Master.master which has a asp Label contol in it. I have used this master page as a template for the after login pages.
I am setting the value of the label on the master page to the session variable of User_Id that is generated after successful login.
My problem is that I have to set the value of the asp Label in the master page manually in the code behind of every after login page I visit.
Is there any way to retrieve the value of the session User_Id directly in/from the master page's code behind rather than setting the value in each and every page's code behind file.
Basically i want to set value of a master page label directly to a session that is generated after successful login. How do I do it?

lbtnSignInTop.Visible = true; lbtnSignUp.Visible = true;
}
else { lbtnSignInTop.Visible = false; lbtnSignUp.Visible = false; } }

Is there a good way to enable forms that come out of user content (CMS) that is displayed inside the form runat="server" tag? All sorts of services provide forms for users to paste into their website, which break if the content ends up inside a .net form. It seems to me that there must be a good way around this, but I can't seem to find any solutions.
