You'll need a couple of things. First, you'll need a web service in your ASP.NET application to "catch" your AJAX post. You can put this service method in your page, or you can make a new web service. If the service method will live in your page, it will look something like this:
<WebMethod()> _
<ServiceMethod(ResponseFormat:=[I forget the namespace].Json)> _
Public Shared Function MyServiceMethod(ByVal property As String) As String
'Do something
'return something
Return 1
End Function
Next, you'll need to use jQuery to make an AJAX post to that web service method. Make sure you use the ClientID of the textbox from which you are grabbing the data you need to send. Also make sure you specify 'POST' as the method, and not 'GET' (which is the default). Something like this:
$.ajax({
url: 'MyPage.aspx/MyServiceMethod',
type: 'POST',
contentType: 'application/json',
data: '{ property : $("#<%=txtMyTextBox.ClientID %>").val() }',
dataType: 'json'
});
Here is the full jQuery AJAX documentation: http://api.jquery.com/jQuery.ajax/

Thanks for your info.I need to pass values from a lot of textbox.So here you are passing only one textbox value.So how can i pass values from a group of textbox
Brandon Montgomery
is it a known number of textboxes? if so, you could add that number of parameters to the web method, and pass each textbox's value into its own parameter...
jQuery.ajax( settings ) : Perform an asynchronous HTTP (Ajax) request.

Yes you can do it. Just get the values from the text boxes and use $.ajax to post the data to the server.
