What does EnableViewState on a HyperLink do or mean?
<asp:HyperLink ID="RegisterHyperLink" runat="server" EnableViewState="false">Register</asp:HyperLink>
What does it mean? and what will it do if I set it to true.
This problem is stopping me from winding up my project. I have a webform where there is a pop-up page that populates one text box and 2 dropdowns. And I also have a checkbox list that does a postback. Whenever the checkboxlist does a postback, one of the dropdownlist's value is reset. It happens with only one dropdown list. The text box and the other dropdownlist retain their value. I have put enableviewstate = true at both the page level and control level.
View 6 RepliesI have set enableViewState to false, why my textbox still remain my last value after i hit the postback button?

What happends if I won't set the enableviewstate property for the second div. Is it inherited from it's parent or not ?
I know how view state works but I do not know how exactly works RegisterRequiresControlState. Where are stored values from control? How exactly does it work?
View 1 RepliesI am trying to avoid enabling EnableViewState..Sample code as you can see has 1 repeater and 2 textboxes inside. I bind the textboxes at page init. After a postback I want to get the updated data from the client & save in a db. The Request.Form contains the data keyed with autogenerated client ids but the repeater has 0 items after the postback. So my options seem limited to.a. Enable viewstate so I can pull the data from the repeater using Control.Find(...)b. iterate through Request.Form and find my textbox values...ultimatly the goal is to to render data from a datatable to some textboxes, allow the user to make changes then save these changes. I'd like to avoid viewstate if there is a clean alternative..ASPX:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Foo.aspx.cs" Inherits="Ads_Foo" EnableViewState="false"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-
[code]...
My dropdown controls do not keep the values after postback even though their EnableViewState is = true and in Page_Load I fill my controls ONLY if not postback.
My controls are inside a panel and the panel's EnableViewState is set to true as well...
To see the page you can log in as test and password is 12345
click on search page and set a value to say Gender and Ethnicity and click submit.
You will see the results, then navigate to number 2 or 3... You will see that it refreshes the controls and sets them to default.
If we set enable view state = false of a page then can we maintain the view state of that page ?
View 1 RepliesWas the new ViewStateMode property introduced to avoid breaking the existing EnableViewState?
Does setting EnableViewState = false at the page level cause the ViewStateMode setting to be ignored?
PS: What is CW in stackoverflow?
I have made EnableViewState="False" in @page directive. But still all all controls in page maintaing values even after submit.

I'd like to implement a hyperlink in many locations on my website, however I just want to have it defined once not several times over. What is the best way to achieve this?I started down the road of listing it in the node of web.config but I was only able to get that to list as a literal and wasn't successful in having it end up as a hyperlink.I don't know much about master pages, but what I do know about them seems to me that they aren't the answer for this task because they wouldn't allow for that hyperlink to be located on some pages and not others and in different locations on some pages than others.
