You can't. ASP.NET is a framework for generating web pages, it has no knowledge of such things. Of course, it's built into C# and VB.NET but that not what you asked.

hello everyone...
i added GetPostBackClientHyperlink in ItemDataBound in ascx file and this is the code
Dim button As LinkButton = CType(e.Item.Cells(9).Controls(1), LinkButton)
If Not (button Is Nothing) Then
e.Item.Attributes("onclick") =
Page.ClientScript.GetPostBackClientHyperlink(button, "")
End If
and i got this error:
Invalid postback or callback argument. Event validation is enabled using
<pages enableeventvalidation="true"> in configuration or <%@ Page
EnableEventValidation="true" %> in a page. For security purposes, this
feature verifies that arguments to postback or callback events originate from
the server control that originally rendered them. If the data is valid and
expected, use the ClientScriptManager.RegisterForEventValidation method in
order to register the postback or callback data for validation.
please help how can i rid at this error 
thanks in advance...

Why in this way ? You can Change the UpdateMode to Conditional and update the panel as UpdatePanel2.Update(),

updatepanel.update() is server side code.

No.
Your Requirement is to update only updatepanel2 which is inside updatepanel1.
So, You can just simple do it.
Set The UpdateMode property of Both the panel to "Conditional" and then you can update any one of them when you wish by UpdatePanel1.update() or Updatepanel2.update()
It will update only particular panel. You don't need any JavaScript for that.

updatepanel.update() is server side code.
When you are updating your post, don't erase original one. It can make the person wrong who answer it.
You had Written some thing like that
"is updatepanel.update() is javascript function " and I said No.
But now you have change your post totaly.
So rather than delete , just do like

not on any click event i just want to raise it like __dopostback('updatepanelname','');
and actually which update panel i want to refresh through javascript is in another update panel and iusing syntax given above refreshes given update panel but also clears values of controls like textboxes which are placed inside parent update panel.
that is what i am facing right now and another thing when i remove parent update panel everthing works fine with full post back but i want to use parent ajax update panel aswell

Hi All,
Being a novice in and have learned C# / ASP.NET for the past year , i would like to find out what is required to start up a good website.
Is there a checklist of things that I need to be able start a website for an idea I have, or is it better that I wait a few years after a few years experience and then pursue that path. Is there such a checklist for things that have to be met when designing a website, and if so what are they?
Kind Regards

1 - A good concept
2 - A good hosting provider with enough bandwidth and HDD storage.
3 - Friendly UI and interactive design
4 - Database. I'd suggest SQL Server or MySQL.

No. Start straight away. That is the best way to get expertise.

So it doesnt really matter how much experience you have?
If my coding skills are not superior then does it still matter?
Ie if I have basic coding skills then is that suffice?

It matters when you are developing a website for a customer which is going to help them for their business or something like that. But it doesn't really matter if you are doing it for learning. And that is the best way to learn things.
All the best
