Method not found after adding code class to SharePoint Web Part

Question

I'm creating a SharePoint Web Part that displays list items.

To display these items I am using an asp:ListView and <%#Eval() %>. I needed to change the output of <%#Eval() %> so I added a new static class to the project, created an extension method and imported the namespace in the user control.

So the <%#Eval() %> looks like this: <%#Eval("xxx").ToString().MyMethod() %>

The problem is that when I debug this Web Part I get an error saying that 'string' does not contain a definition for MyMethod.

You have to try it different way:

• In your ascx.cs file, declare a public method

public string Abc(DataRowView row) {
return  row["xxx"].ToString().MyMethod()
}

• call this function from list view like:

<%# Abc(Container.DataItem) %>

This should work.
