Access value of HiddenField in static WebMethod in ASP.Net

Hi usman,

You have to declare a static variable and then assign that variable to hidden field.

I have a sample code below. Please refer that.

Code

public static int TestId = 0;
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        TestId = 140; //Asigning the vale
        hfId.Value = TestId.ToString();
    }
}

[WebMethod]
public static int InsertTest2(Test2 test2)
{
    try
    {
        int no = 0;
        if (TestId != 0)
        {
            string strConnString = ConfigurationManager.ConnectionStrings["TestEntities"].ConnectionString;
            SqlConnection con = new SqlConnection(strConnString);
            SqlCommand cmd = new SqlCommand("Test2_SaveTest2", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@TestId", TestId);
            cmd.Parameters.AddWithValue("@Age", test2.AGE);
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
            con.Dispose();
        }
        return no;
    }
    catch
    {
        return 0;
    }
}

Hope this will help you.
