question about viewstate

Francis

Hi,

i'm testing ViewState with this page here below:
i tried with EnableViewState ="false" and with EnableViewState ="true", but
the produced source code is the same in both cases. I would expect here no
hidden" name="__VIEWSTA TE in the source because of 'false' ...

If someone could explain this.
Thanks
Francis

aspx page:
<%@ Page Language="VB" EnableViewState ="false" AutoEventWireup ="false"
CodeFile="Defau lt.aspx.vb" Inherits="_Defa ult" %>

<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"> </asp:TextBox>
</div>
</form>

It keeps an information about 1) view state data and 2) control
hierarchy. And even you turned a viewstate off 1) you will still have
that hidden field because of 2)

ViewState question - for tech-heads only

Say I have persisted a DataSet in the ViewState of a page, and that when the page is posted back I make several references to that dataset like so: DataSet MyDataSet = (DataSet)ViewState; //C# Does this have to deserialize the dataset every time it is referenced... or is it only done once when the page is posted back? I'm just wondering if I should assign the DataSet to a local variable in the PageLoad method or if it's OK to...

enableviewstate=false question

I've created two textboxes and one button on my web form. I then set the EnableViewState property of Textbox1 to False. Textbox2 is set to True.

I click the button and the page reloads. Textbox1 has the value of "test 1". Textbox2 has the value of "test 2". Am...

I can send data with no problem (using VXML submit with method post) but at the server IsPostBack is always false. How does the server determine if it is a PostBack? I...

Label ViewState question

by: Mark Olbert | last post by:

I have a composite control (under ASPNET2; derived from CompositeControl) which contains a label. The contents of the label are set when the control is created to a user-supplied value. What's confusing me is that on postback the contents of the label are not being restored from ViewState. I thought that happened automagically...but I guess not. I'm obviously missing something really simple. How do I get the label to set its text from...

ViewState question

by: Carly | last post by:

Hi, I am now not sure I understand what ViewState does. Having EnableViewState=true or false on a WEB form and/or different server controls does not seem to make any difference. I am just playing around with VS 2005 and no matter the value of EnableViewState all the controls maintain their value. Can anybody explain or point me to a clear article about this subject. Much appreciated,

Same question - Why use a DataTable in ASP .NET?

by: jehugaleahsa | last post by:

Hello: What is the point of using a DataTable in ASP .NET? We are unsure how you can use them without 1) rebuilding them every postback, or 2) taking up precious memory. We are not sure how to store a DataTable in any other way outside of our servers. In doing so, we leave ourselves open to large memory requirements. Furthermore, most web pages do not really support multiple changes per transaction. In other words, when the user submits...

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
