Question

I am trying to do simple data entry. I have my aspx file for input and data manager file in App_Code folder to interact with data entity. I have “static” add method but I cant add the model file with “using dataModel” line and cant call the static method in code behind…

What am I missing?

main.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using dataModel;     // <------------- cant add this one..gives error

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

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        dataManager em = new dataManager();
        em.add(...)
    }
}

dataManager.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

public class dataManager
{

    // Add a new customer
    public static void add(...)
    {
    .
    .
    .

Static methods are not called on instances. The following will work:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

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

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        dataManager.add(...);
    }
}
