Accessing Data in Objects Using Eval in ASP.Net

Question

Say I have the following classes:

public class A
{
    public string x;
}

public class B
{
    public A a;
}

I then bind my repeater to a list of class B's. Is there any way using Eval that I can get class A's x data member?

For example, Eval("A.x"). I know that won't work, but just curious if there was a convention for doing this.

I've looked at this post, but I don't believe it actually answers my question.

Have you tried doing this, but using properties rather than public members? — Daniel Bradley

Please avoid the asp tag... you know, the one with the big "DO NOT USE" message in the help text when you select it. — Joel Coehoorn

I have not done it using the syntax in the referenced post, but I have done this:

((A)Eval("A")).x

if I have properties.

You could wrap your Eval in a function that returns the data you're after

<%# PullDataFromObject(Eval("B")) %>


Protected A PullDataFromObject(B myObject)
{
    return B.a;
}

or something like that .. not compile checked etc
