I have a grid where I've set one of the columns to use a template and call to a function for its value. What exactly does Eval do?

<ItemTemplate>
                    <asp:Label ID="AuthorizedLabel" runat="server" Text='<%# GetBooleanText(Eval("Authorized")) %>' />
                </ItemTemplate>

It's short for Evaluate. It basically means "see if you can find a property on the datasource with the specified name, and put its value here".

Carl is absolutely correct.  It is also important to note that the Eval function will return the value of the property boxed in an object.  If you want to do some sort of logic with the value (such as dynamically determining if a textbox is visible), you will have to cast it to the appropriate type first.
