Question

I would like to call my Public String Function(...) method from my .ascx‘s Page_Load event. The function and containing class are located in the same code behind as the web control. But I am unable to access the function. How can I resolve this problem?

Example:

public class Controls_WebApp : System.Web.UI.UserControl, IAttributeAccessor, IUserControlDesignerAccessor
{
    protected void Page_Load(object sender, EventArgs e)
    {
        // Call Function
    }
}

public class A
{
    public string Function(string path)
    {

    }
}

As it stands you will need an instance of A to invoke the method

using namespaceOfA;
...
string result = new A().Function("Hello world");

Alternatively if the function has no reliance on the state of A, you can make the function static (public static string Function)

string result = A.Function("Hello world");
