Using the Eval method in a SharePoint master or layout page

Examples of using Eval method in SharePoint master or layout page:

In this example "Include Time" is a SP yes/no field where we're checking for a value of "yes":

<%# Eval("Include Time").ToString() == "True" ? " (" + Eval("Start Time","{0:hh:mm tt}") + ")" : "" %>

In this example "Active" is a SP yes/no field where it's casted to a boolean value and then used to control visibility of an asp:Label control:

Visible='<%# bool.Parse(Eval("Active").ToString()) %>'

Another example of setting the Visible property. If the value of Descrition is null, hide the control:

Visible='<%# bool.Parse(Eval("Description") == null ? "False" : "True") %>'
