Response.Write("Page Load:");
}
public string setContext(string sName, string sVal)
{
HttpContext.Current.Items[sName] = sVal;
return sVal;
}
public string getContext(string sName)
{
string sVal = "default";
if (HttpContext.Current.Items[sName] != null)
sVal = HttpContext.Current.Items[sName].ToString();
else
sVal = "empty";
return sVal;
}
</script>

I need to get the context value in top of page, where the context value will be set at the bottom of the page.
- Get context value ==> "empty", BUT need "something"
- Set context value to "something"
- Get context value ==> "something"
I may use JS/AJAX, where the page source the value won't be present.
BUT I need the TEXT in the View Source of the page too.Is there a way to wait for the context to set and then get, I have tried with User Control, prerender and render methods too. But I can't able to get it right.
Any idea?
Your code executes in the order that it appears.
Therefore, your getContext call is run before the call to setContext.
What are you trying to do?
