Question

How can I disable viewstate in my ASP.NET page for most controls, but allow some controls to still use ViewState?

I have tried:

• In the properties I change EnableViewState=false
• Use <%@ Page Language="C#" EnableViewState="false" ... > at the top of the page

But how do I enable some controls to still allow viewstate?

I am using .NET 4.

I found a way, but only use this in the .NET framework 4. Put this in page directive:

<% ----    ViewStateMode="Disabled" %>

and use this for each controls that want to save the Viewstate (For example):

<asp:DropDownList ID="comGrade" runat="server" ViewStateMode="Enabled">
</asp:DropDownList>
