Question

I have 3 ASP.NET pages. Each has its own GetSearchResult method, which produces a different search result and fills a GridView. Each page calls a shared helper method from a helper class.

Now in this helper class, I want to execute that GetSearchResult method that belongs to on the page that called the helper method.

Is this possible? And if so, how should I do this?

Answer 1

Pass in an instance of the class that owns the method GetSearchResult as a parameter to your helper method. This will give the helper method access to the callers methods. You will need to implement an interface to do this.

public interface ISearchable
{
    void GetSearchResult();
}

public class MyPage : Page, ISearchable
{
    public void GetSearchResult() {
        HelperClass.HelperMethod(this); // Pass in
    }
}

public static class HelperClass
{
    public static void HelperMethod(ISearchable page) {
        page.GetSearchResult();
    }
}
