Best Technique for Multiple Eval Fields in Gridview ItemTemplate?

问题

What is the best way to use multiple EVAL fields in a GridView ItemTemplate?

Looking to have some control over formatting for appearance as well as setting up hyperlinks/javascript etc.

回答1:

Even clearer, IMO, is:

<%# String.Format("{0} - {1}", Eval("Name1"), Eval("Name2")) %>

回答2:

I had previously used this (bad, I know):

<%# Eval("Name1", "{0} - ")%> <%#Eval("Name2")%>

Result = 'John - Smith'

But just discovered that I can also put TWO (or more) Evals in the same data-bound group:

<%#Eval("Name1") & " - " & Eval("Name2")%>

Result = 'John - Smith'

Or

<%# "First Name - " & Eval("Name1") & ", Last Name - " & Eval("Name2")%>  

Result = 'First Name - John, Last Name - Smith'

回答3:

Eval and Bind both suck.
Why get the property through reflection? You can access it directly like this:

((MyObject)Container.DataItem).MyProperty

It's not like the object is unknown to you at runtime. That's my two cents, anyhow.

回答4:

I have a easiest way to do this same thing...

<asp:Label ID="lblName" runat="server" Text='<%#Eval("FirstName").ToString() +", "+ Eval("LastName").ToString() %>'></asp:Label>

.

<%#Eval("FirstName").ToString() +", "+ Eval("LastName").ToString() %>

Here both objects are converted into string the concatenate them.
