hi all,

page name :test.ascx

$.ajax({
            type: 'POST',
            url: 'test.ascx/GetRandomSalt',
            contentType: 'application/json; charset=utf-8',
            data: {},
            dataType: 'json',
            async: false,
            success: function (r) {
                result= r.d;
                document.getElementById('<%=hdnRandomKey.ClientID %>').value = result;
                callback(result);
            }, error: function (x, e) {
                alertify.alert("Server not responding, Please try again later.")
            }
        });

here i have used this test.ascx user control in three various aspx pages in another folder

in ADMIN folder
----------------
first.aspx
second.aspx
third.aspx

these three aspx pages having test.ascx

in USERCONTROL folder
----------------------
test.ascx

both ADMIN folder and USERCONTROL folder are in same path


problem is if i placed the webmethod in first.aspx.vb its working fine(it means i have to write the same code in three pages know). Instead of that i placed the webmethod in test.ascx.vb file means its not working.

Requirement is I need to write the webmethod in test.ascx it easy to handle three pages

Thanks in advance,
Vels
