ViewState is used to persist the values in the same page during the page postback. You cannot use ViewState to pass values from one page to another. You can do Cross Page PostBack to access the values of server controls in the target page (as Christian said) or you can use Query String.

Does anyone has any experience in using Scrtip#, the C# to Javascript converter[^] , which is created by Nikhil[^], a software architect from Microsoft?
I was playing a lit bit with Script# and I have some thoughts that I wanna share you and I wanna hear about your thoughts too... (I'm not so sure whether I should post it in Lounge or ASP.NET forum so the admin feel free to move this thread to the appropriate forum. )
First of all, I wanna say "thank you" to Nikhilk for creating this (no matter whether I use it or not) because the Java developers have this kinda tool (GWT) that can convert the Java code to Javascript. Now, We, the C# developers, got the same thing now. 
1. The advantage of using Script# is that it supports the compile-time checking, IntelliSense so that it's very easier for those who are not so familiar with Javascript.
2. Script# is able to convert the C# code to Javascript but it doesn't mean that it can convert all C# code. In order to convert the C# to Javascript via Script#, we have to write the Script#-specific code in C# then those codes will be converted to Javascript... (So, I think that Script# is NOT 100% C# to Javascript Converter. )
3. The GWT is developed by Google and Script# is not developed by Microsoft. It has too much differences. Even thought Nikhil is an architect from Microsoft, Script# is just his pet project.. So, he can't support his pet project all the time.. I have checked Script# discussion[^] and found that there is no active contribute (including Nikhil). The community is so small if we compare to GWT community.
4. Script# is not Opensource. 
5. In order to use Script#, you have to understand about how Script# works (of course) and the syntax of Script#. It's not so similiar to the Javascript.
If you are alreadys fimiliar with Javascript, you won't be so happy with Script# because ~
5.1. All syntax that are available in Javascript might not be available in Script#. OR it is so hard to find the equivalent Script# .
For example: How to access 'document' of created DOMElement??[^]
In Javascript,
<br />
var iframe = document.createElement("iframe"); <br />
var doc = iframe.contentWindow.document; <br />
In Script#,
using System;<br />
using System.DHTML;<br />
using ScriptFX;<br />
using ScriptFX.UI;<br />
<br />
public class MyScriptlet {<br />
<br />
public static void Main(ScriptletArguments arguments) {<br />
DOMElement _iframe = Document.CreateElement("iframe");<br />
DOMElementExt contentWindowElement = (DOMElementExt)_iframe.GetAttribute("contentWindow");<br />
DOMElement doc = contentWindowElement.document;<br />
<br />
}<br />
}<br />
<br />
[IgnoreNamespace]<br />
[Imported]<br />
public class DOMElementExt : DOMElement {<br />
<br />
[IntrinsicProperty]<br />
public DOMElement document {<br />
get { return null; }<br />
}<br />
<br />
[IntrinsicProperty]<br />
public DOMElement body {<br />
get { return null; }<br />
}<br />
<br />
[IntrinsicProperty]<br />
public DOMElement src {<br />
get { return null; }<br />
}<br />
<br />
[IntrinsicProperty]<br />
public DOMElement firstChild {<br />
get { return null; }<br />
}<br />
}<br />
If you look at both examples, you will understand how hard to find the equivalent syntax in Script# (sometimes). I understand that it is kinda hard for Nikhil to add all Javascript equivalent systax to his framework..
6. Script# does support the compile-time validation but the problem is that you won't be able to debug the C# code that you wrote. Instead, you will have to debug the Javascript code that generate by Script#. I think that it is the big issue for web developer.
7. The most of Javascript libraries /framework (e.g. prototype, script.aculo.us, Yahoo.UI, ExtJS) are not written in Script#. So, If you wanna use those libraries in Script#-enabled project, you will have to create a wrapper that can take a lot of time...
8. Script# might be good for ASP.NET Ajax developers and Vista Gadget developers. As I'm not very familiar with those things, I'm not able to cover about this. I need your contributes for this fact.
That's all from my side.
As Dimitri said here,
"if you can't handle Javascript, you shouldn't be writing code for Web applications. HTML, CSS and Javascript are the three prerequisites for this ride."
I agreed with his answer..
Could you please share your thoughts about Script#?

Here are my thoughts: That's a really long post.  No problem... usually after my stupid comments, someone out there takes a look at your post and replies with something useful, which makes me feel like I'm totally useless. 
As for Script#, all I can say is that if it really can do what it's supposed to do, It would be really useful in porting a lot of applications(I only read the first few lines of your post ). However, my belief in script-based languages has yet to be incurred.

You can use the Session object or Cache object to store those values....

Yeah. You can use the Session object.
koolprasad2003 wrote: can it use my server memory
All variables use the memory. For example: int i = 0; If you declare the variable called i, it will take some amount (maybe. very little) of memory... Nothing on computer works without memory.
koolprasad2003 wrote: what abt Viewstate?
The ViewState is not for that purpose. Don't confuse.

You can Tamper[^] the Query String values and Pass to another page, use Response.Redirect()

I think I've seen this thread earlier.
Are you sure the function works fine?? Because i think that the SQL statement looks strange to me..

This code is working fine??
I don't have VS 2003 in front of me.. I will tell you some possibilities..
Try with only one textbox
1. You said that the textbox "acSearch" and "GetSearchData" work fine. Why don't you try with "acSearch" and "GetSearchData1"
<br />
acSearch.PageType = Me.[GetType]().BaseType<br />
acSearch.OnAutoComplete = New Autocomplete.AutoCompleteHandler(AddressOf Me.GetSearchData1)
Is it working?
2. What about "Autocomplete1" and "GetSearchData"?
<br />
Autocomplete1.PageType = Me.[GetType]().BaseType<br />
Autocomplete1.OnAutoComplete = New Autocomplete.AutoCompleteHandler(AddressOf Me.GetSearchData)
Is it working?
3. What about "Autocomplete1" and "GetSearchData1"?
<br />
Autocomplete1.PageType = Me.[GetType]().BaseType<br />
Autocomplete1.OnAutoComplete = New Autocomplete.AutoCompleteHandler(AddressOf Me.GetSearchData1)
Is it also working??
If those three possibilities are working fine then try with two textboxes..
1.
acSearch + GetSearchData
Autocomplete1 + GetSearchData
2.
acSearch + GetSearchData1
Autocomplete1 + GetSearchData1
3. (finally)
acSearch + GetSearchData
Autocomplete1 + GetSearchData1
And let us know the steps the code is not working.
One more suggestion. If you are testing those steps, I suggest you to use Firefox with Firebug. And check whether you got any error in Firebug console or not..
