I am using PageMethods to call server side method from client side but I am getting a problem that server side method is calling only if, I am calling the method from source part, if i am making a javascript file with the same javascript code and adding the link into the page then it is not working, only PageMthods is not working but all other thing of javascript file is working fine.

Please suggest how would I resolve this issue.

Thanks

My first guess would be - the URL isn't correct. Can you show your javascript code which is calling the pagemethod?

Hi Friend,

It should not affect weather keeping script in page level or in script file.
Check once weather you gave right file or any other syntax.

it is good to find the error with Firebug..!

using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    [System.Web.Services.WebMethod(EnableSession = true)] 
    [System.Web.Script.Services.ScriptMethod(UseHttpGet = false, ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)]
    public static string yourmethod1()
    {
         return "Allow user";
    }
}

        }
        function OnSuccess(response)
        {
            alert(response);
        }
        function OnError(error) 
        {
            alert(error);
        }

            <input id="Button1" type="button" value="button" onclick=" return GreetingsFromServer();" />

    </div>

    </form>
