Visual Studio .NET - Using C# variable in javascript function?

Hi all - I need to use a c# integer in a javascript function, e.g
[CODE]
<script language="JavaScript">
function TargetDate()
{
	targetNumber=getQueryString("tnum=","xxxyyy");	
}
</script>
[/CODE] 
where "xxxyyy" is a c# integer that I get from a database and pass into the javascript somehow - is this possible?

Hi,
How can a server side variable be accessed on client side?
I don't think it is possible to directly access C# variable in javascript code. If you get anything about this please share with me.
Instead you can save value of C# variable in hidden field on the form and then access that field value in javascript.
[CODE]
<INPUT id="hd" style="Z-INDEX: 101; LEFT: 16px; POSITION: absolute; TOP: 144px" type="hidden"  value="<%=strvariable %>">
<script language="javascript">
function Button_Click()
{
	alert(document.getElementById('hd').value); 
}
</script>
[/CODE]

explore the RegisterStartupScript and RegisterClientScriptBlock methods:
 http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspp/html/aspnet-usingjavascript.asp
This snippet demonstrates use of RegisterStartupScript method
Page.RegisterStartupScript("MyScript",
   "<script language=javascript>" +
   "function AlertHello() { alert('Hello ASP.NET'); }</script>");
Button1.Attributes["onclick"] = "AlertHello()";
Button2.Attributes["onclick"] = "AlertHello()";
 This snippet shows how to access a C# variable through javascript, after the page loads.
private void Page_Load(object sender, System.EventArgs e)
{
	String myString = "Hello C# World";
	Button1.Attributes.Add("onclick","javascript:alert('" + myString + "')");

not really what I'm after. I have a very large block of javascript code that executes when the page loads. I need to "inject" a c# integer (grabbed from a database) into that javascript code.
Hopefully the technique that was mentioned in the first reply will work...will give it a try this afternoon
Thanks again,
James

Another method:
code behind:
public int c_integer=0;
assign c_integer form the db
HTML:
<script language="javascript" type="text/javascript">
var c_int=<%=c_integer%>;
</script>
Then use the var as needed.
Hope this helps, it works for me.

Thanks Paul - this is exactly what I was after

Paul,
That was very helpful, thanks a bunch. Was wondering if you knew how to access C# array variables from Javascript. I tried but in vain...
Thanks,
Aj

AJ, without knowing exactly what you need, here's what I do:
	Declare a public string variable.
	Fill the string variable with a known character seperating values, i.e., variable+=value+",";
	On client-side, assign a javascript variable to the C# variable.
	Use the javascript method split to create the javascript array.
	Iterate thru the array to retrieve the results.
	Here's an example:
		[CODE]
		var c_var="<%=variable%>"; // variable being the C# public string variable
		var js_array=c_var.split(",");
		for(i=0;i<js_array.length;i++){
			alert(js_array[i]);
		}
		[/CODE]
The seperator used in the C# between results is the same seperator used in the javascript split method.
I hope this helps and good luck,

Paul,
Thanks a ton for the prompt reply. Your solution works fine. Needed to store the array in a string as you said instead of an typed array.
Thanks,
Aj
