AJAX[^] is the answer. To make things easier, use AJAX toolkit for ASP.NET. :)

What the hell is wrong with you? You ask a question, you're given the de-facto answer and you want a different way of doing it just because you're not familiar. How do you think people learn new concepts?

I would prefer you to use AJAX but here is one other solution. From javascript make a call to dopostback method with eventtarget and arguments (if reuqired) and in Page Load method check for the event target and call the C# method. Remember this is dirty trick. JavaScript (JS File)

__doPostBack('CALL_MY_METHID','');

ASPX Code Behind

void Page_Load(object sender, EventArgs e)
{
....
....

// Insure that the __doPostBack() JavaScript method is created...
this.GetPostBackEventReference(this, string.Empty);

string eventTarget = (this.Request["__EVENTTARGET"] == null) ? string.Empty : this.Request["__EVENTTARGET"];
if (eventTarget == "CALL_MY_METHID")
{
// Call your C# method here and return
CallMyMethod();
return;
}
....
....
}

Be careful, there is no Undo Button(Ctrl+Z) in life.

.NET is parsed by the server. Javascript is parsed by the browser. If you have page that is already loaded that you want to process a .NET page, asking the server to do so via Javascript is the best way. Ranjit Viswakumar Professional Services Specialist HostMySite.com[^]
