I sent the parameter 'q' using javascript using the AJAX as

C#

var sendingStr = "Default.aspx?q=" + document.getElementById('q').value;
xmlHttpRequest.open("GET", sendingStr, true);

=============================================================================

now, using C# on my Default.aspx page, i want to get the 'q' parameter's value.

I searched web. it was somewhat talking like...

qStr = Request.QueryString["q"].ToString();

i debugged. its showing qStr as empty

it did not worked. Where's the error?

How can i get that parameter?
