No overload for method 'Eval' takes '4' arguments

[DaveRook]

Any ideas with this?

HTML page

<%#loc(Eval("B", "U", "M", "S"))%>

code behind

public String loc(object o1, object o2, object o3, object o4)
	{
		string s = Convert.ToString(o1) + Convert.ToString(o2) + Convert.ToString(o3) + Convert.ToString(o4);
		return s;
	}

The B U M and S are objects from a database. At any point, only 3 of the 4 objects will have content. Could this "No overload for method 'Eval' takes '4' arguments" error be casued due to a value returning empty or null from the database?

No. Its saying that your Eval method doesn't take 4 parameters.

Please show us the code for your Eval method and we'll see if we can help out.

This has confused me! All the code is above!

I often use <%#method(Eval( "columName" ))%> and the method is in the code behind (in the above example a public string function)

For example, this works:

html

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

codebehind

public String loc(object o)
{
string s = Convert.ToStrin g(o);
return s;
}

I just want to do the above with 4 objects in the parameters

Sorry if being dense

I solved it by changing to
<%#loc(Eval("B" ))%><%#loc(Eval ("S"))%><%#loc( Eval("M"))%><%# loc(Eval("U"))% >

I wanted to do the 4 statements as 1 but doing it like this is fine.

Thanks

Glad you solved the problem :)
In the future, please remember that when you're binding, you can only bind to 1 thing at a time.
