I have customized my AppointmentTemplate by adding some controls (Labels and ImageButtons).
I need to access those controls to change values based on info I have in my Appointment object.
My first approach was just using Eval() to toggle the visibility of a LinkButton in the markup based on a custom attribute like this:
            <AppointmentTemplate>
                <p>
                    <h2><%# Eval("Subject") %></h2><br />
                </p>
                <p>
                    <h3><%# string.IsNullOrEmpty(Eval("Attributes['gst_name']").ToString().Trim()) ? "" : "with: " + Eval("Attributes['gst_name']") %></h3>
                </p>
                <p>
                     <asp:ImageButton id= "ibNotes" ImageUrl="~/Images/note.png" runat="server" CommandName="GetNote" Visible = "<%# Eval("Attributes['notelength']") = "0" ? "false" : "true" %>"/>

                </p>
                <p>
                    <h3>AppointmentTemplate<%# Eval("Attributes['modifiers']") %></h3>
                </p>
            </AppointmentTemplate>

But I can't build with it this way. I get an error: "The server tag is not well formed." Referring to my ImageButton location.

So I tried another approach, to get to it in codebehind, but I can't get anything working there either.
What server side event should I use? I'm thinking I'd need to use FindControl() but can't find anything in Intellisense.

Anyone got an example?

Thanks!

Hello Matt,

I am not sure if you have seen the new demo on Customizing the Appointment. Probably, it can help you resolve the problem.

Let me know how it goes.

All the best,
