The major difference is that preinit is fired first. It was added just to give finer grained control.
LoadViewState won't fire unless you're posting back, as there can't be any viewstate to load.

It will be stored in viewstate, so long as viewstate is turned on for the page and the control.
vikasviswan wrote: what is diff b/w data stored in view state and data stored in a control that implements IPostBackDataHandler.
Probably nothing, viewstate is the only state in town, except control state, which is just a subset of what 1.1 stored in viewstate, so you can turn some of it off and not the rest. Control state is really still viewstate.

i have a textbox and 2 buttons.
In the first button click ,i am changing the textbox value to hello.
Second textbox is just doing a postback no code.
Code is below
protected override void LoadViewState(object savedState)
{
base.LoadViewState(savedState);
}
protected void Page_Load(object sender, EventArgs e)
{ }
protected void Button1_Click(object sender, EventArgs e)
{
TextBox1.Text = "Hello";
}
protected void Button2_Click(object sender, EventArgs e)
{ }
I turned Enableviewstate of page to false;
I noticed that when i click the first button textbox value changes to "hello" and when i click the second textbox it is still retaining the value "hello". How is this possible without viewstate ..
Then i turned Enableviewstate to true. In both cases LoadViewState is never called, i tried a lot...Can u pls give me a sample example where LoadViewState would be called

Perhaps the text is stored in control state ? That's possible, I'm not that sure of what goes in there.
I'm about to go out, otherwise I'd whip up a sample for you. I recommend googling for LoadViewState.

Regarding difference between VIEWSTATE and CONTROLSTATE, one differnec which i am aware of is, VIEWSTATE can be handled, edited, accesed by programmer while CONTROLSTATE can not be accessed, edited or disabled directly but it is maintained by .NET framework.

Consider using a sensible subject in future. Odds are, your question in this forum, relates to ASP.NET.
Your first step is probably to tell us what *does* happen, does it blow up, does it do nothing ? I mean, if this is an active X control that is installed on the machine yuo're using, it should work, to know why it's not, we need to know more details than 'I am unable to display the image'

Shouting[^] won't make your question any easier to understand.
I'm gonna go out on a limb here and assume you can't see a particular control in your toolbox that you're expecting to see. Try right-clicking over the toolbox, selecting "Choose items...", browse to the library containing the control & opening.
That said, bear these two thoughts in mind:
1. Are you sure there is a control in that library that you can add to your toolbox?
2. You want to place this on a Web form - chances are the people accessing your web form won't have the ability to see this control on the client side so what exactly are you trying to gain?

hi all,
Now I am working on Asp.net 2003 .
My problm is, in some pages, the load event is not working.
Somtime it wrks very fine but in certain time surprisingly the load event is not triggered.
At the same time , this pblm not affected to the other forms too.
what should I do?
Now i solve this problm by creating a new webform and copy the old from contents to new page and continue my work..But this is a tedious process and time consuming one.I didnt think this is the exact way...
thanks in advance.
All I ever wanted is what others have....

Are you overriding the event, hooking it up in your init, or just letting it associate automatically ? The only reason for it not to fire, is that it's not hooked up properly.

There is a problem in VS 2003, where it sometimes removes the code that hooks up the handler with the event.
Look at the autogenerated code in the code behind file, and see if hooks up the Load event. If not, copy the code (might need adjustment for page name) from a page where it's working.

Oh, you want an IMMEDUATE solution. So, not like the other people asking here, who were hoping to wait a week ?
A sensible subject is likely to attract people to help you. A dumb or rude one is likely to cause people not to bother looking.
To make a bitmap on your page, you need to create a bitmap on the server side, and push it down.
To make it interactive, ASP.NET won't help you, it generates HTML, and HTML can't do that. Flash can, so can SVG and WPF-E, or whatever they call it now.

Silverlight[^]. I really think MS is trying to poke at Flash with the name.

hi,
I would like to load a web user control at runtime in my ATLAS enabled application, so i placed a placeholder inside atlas:UpdatePanel tag and coded as following :
<code>
<atlas:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:PlaceHolder ID="pHolder" runat="server"></asp:PlaceHolder>
</ContentTemplate>
</atlas:UpdatePanel>
<%
MYCTR myctr = (MYCTR)LoadControl(@"~\CTR\PRODUCTS\ProdItem.ascx");
pHolder.Controls.Add(myctr);
%>
</code>
At runtime it throws an unspecific error.
Advance Thanks.

Hi, do you know of a simple VB.NET code for username and password validation that does not involve the use of stored procedure or appsetting? I've found several that use stored procedures and other complicated stuff that I don't yet understand. I'm new to web development and I'm trying to go from the really simple stuff to the more advance stuff one step at a time. It would be great if you could point me to an online tutorial. Thanks in advance for your help.
