Extract ID in AppointmentTemplate

[Peterson Mwangi]

Hi coders,
I have a <a> tag in the AppointmentTemplate and when a user clicks on the link, I would like to extract the ID of the clicked entry and pass it to a javascript function. This is the code I am trying but it doesn't work. Please let me know how to accomplish this:
 

<AppointmentTemplate>
   <div>
      <a href='#' onclick='openWindow(<%# Eval("ID") %>)'><%# Eval("Subject") %></a>
   </div>
</AppointmentTemplate>

openWindow is my JavaScript function. Please let me know where I am going wrong.

Thanks, Peterson.

Hi Peterson,

How do you bind RadScheduler? How do you set the DataKeyField property?

Hi Peter,
I am binding the scheduler programatically in the page_load event, see below: 

calendar.DataSource = dtEventDates;
calendar.DataKeyField = "event_id";
calendar.DataSubjectField = "subject";
calendar.DataStartField = "start_time";
calendar.DataEndField = "end_time";

calendar.DataBind();

Thanks,
Peterson

Hi Peterson,

Can you try the following and let me know if it helps:

<AppointmentTemplate>
   <div>
      <a href='#' onclick='openWindow(<%# Eval("event_id") %>)'><%# Eval("Subject") %></a>
   </div>
</AppointmentTemplate>

Sincerely yours,

I need help on this one too.  This suggestion did not work.

I am trying to make a link to a form, but i can not get the ID out of the calendar.

 <a href = "TaskView.aspx?id=<%# Eval("ID") %>&a=<%#Eval("Account.Selectedvalue")%>"><%# Eval("Subject") %></a>

I have declared

DataKeyField="TaskKeyID"

but   <%# Eval("TaskKeyID") %>   does not work either

David,
This is how I resolved the issue:
On the RadScheduler, add the client side event handler for OnClientAppointmentClick, as shown below:

OnClientAppointmentClick="onAppointmentClick"

The "onAppointmentClick" is a JavaScript function which is as shown below:

function onAppointmentClick (sender, eventArgs) {
    var id = eventArgs.get_appointment().get_id();
   // rest of the code goes here.
}

Once you have the ID then you can manipulate as you wish.

Hope this helps.

Peterson.

I am trying to get the link to display in the calendar view before it is ever clicked on so a link shows in the Appointment template.

This should be simple and i am sure my answer will be once i find it.

David,

This should give u a link on the appointment:

<telerik:RadScheduler ID="calendar" runat="server" OnClientAppointmentClick="onAppointmentClick">
    <AppointmentTemplate>
        <div style="cursor:pointer; color:blue;">
            <%# Eval("Subject") %>
        </div>
    </AppointmentTemplate>
</telerik:RadScheduler>

Replace "Subject" with your actual Subject field. There may be other ways to achieve the same, but that was my approach.

[Peter]

Likewise, this will extract the ID in the appointment template:

<AppointmentTemplate>
         * * *
          <%# Eval("ID") %>
      </AppointmentTemplate>

Best wishes,

Look how simple.  i swear i tried that. - If I simplify my link that worked !!

my example even had that in it.

<a href = "TaskView.aspx?id=<%# Eval("ID") %>&a=<%#Eval("AccountNumber")%>"><%# Eval("Subject") %></a>


Now ----

Is there a way to eval  - just plain old fields from the data source that are not mapped to resource controls ?
In my task database there are linked ID numbers. for Service order, Work Order, Quote,  etc. - There is no need to assign them a datasource with a drop down.  These fields are read only in my task table, but if the task is related to another document i want to show a link in the template

for example SONumber  is a field in the data source

<a href = "SOView.aspx?id=<%# Eval("SONumber") %>&a=<%#Eval("AccountNumber")%>"><%# Eval("SONumber") %></a>

When i try to reference that field it says -
Error Message: DataBinding: 'Telerik.Web.UI.Appointment' does not contain a property with the name 'SONumber'.


Thank You !!

Hey i will answer my own question this time.


I added   

CustomAttributeNames="SOnumber,QuoteNumber,WOnumber"

to the control declaration -  EZ!  then i can read any of those fields into my template.

This scheduler is going to be a n awesome addition to my project !!!

But i do have one more ....
Can I make parts of that conditional ?  i only want to show the SOnumber link if it has data in it.
It does not like me throwing in <%  IfEval("SONumber") <> "0" Then%>  .....  <% End if %> in the template

<AppointmentTemplate>
         <a href = "taskview.aspx?ID=<%#Eval("ID")%>&a=<%#Eval("AccountNumber")%>"><%#Eval("Account.Text")%> - <%# Eval("Subject") %></a>

         <a href = "soview.aspx?ID=<%#Eval("SONumber")%>&a=<%#Eval("AccountNumber")%>"><%#Eval("SoNumber")%></a><br />

         <%#Eval("Start", "{0:t}")%> -
         <%#Eval("End", "{0:t}")%><br />
         <%#Eval("Description")%><br />

    </AppointmentTemplate>

Ok so maybe i should think a little more before posting

I got the conditional binding to work like this.

                         

  <%#IIf(Eval("SONumber") <> "0", "<a target = _new href =  ""soview.aspx?id=" & Eval("SoNumber") & "&a=" & Eval("AccountNumber") & """>SO#" & Eval("SoNumber") & "</a><br>", "")%>
