Thank you very much for the response, sorry i didn't explained my issue in detail in the last post.
Actually I have some more fields in the appointment table, i.e. SupplierId and Supplier Name, I have to show data of these in the appointment text area. I tried using below code in the AppointmentTemplate but it returns error:
# Eval("cSupplierId") %>
I want use the AppointmentTemplate to like below:
<b><%# Eval("Subject") %></b>
<asp:Label ID="lblEdit" runat="server" />
This lblEdit label's text will be set at runtime.
