I have a scheduler component and I want a custom insert view. Is it possible to get controls from the AdvancedInsertTemplate? I tried using FindControl on the scheduler component but with no luck. So is the recormended way to get all selected values from a ListBox places in the AdvancedInsertTemplate? I guess that custom attributtes dosent support multiple values? Same if I used a gridview how do I get the values from that?

protected void RadScheduler1_AppointmentInsert(object sender, Telerik.Web.UI.SchedulerCancelEventArgs e)
            string test = e.Appointment.Attributes["Test"];            
            ???? here to get values from listbox???

    <telerik:RadScheduler ID="RadScheduler1" runat="server" Height="583px"
        Width="889px" onappointmentcreated="RadScheduler1_AppointmentCreated"
        onappointmentinsert="RadScheduler1_AppointmentInsert" CustomAttributeNames="Test,Test2">        
        <AdvancedInsertTemplate > 
            <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Subject") %>'></asp:TextBox>
            <asp:ListBox ID="ListBox1" runat="server" SelectionMode="Multiple" SelectedValue='<%# Bind("Test") %>'><asp:ListItem>dsdsd</asp:ListItem><asp:ListItem>sdsdsd</asp:ListItem></asp:ListBox>
            <asp:LinkButton runat="server" ID="UpdateButton" CssClass="rsAdvEditSave" CommandName="Insert">Insert</asp:LinkButton>

Hello thomas,

You can get the listbox client-side object from the AdvancedInsertTemplate via this:

var listbox = $find("RadScheduler1_Form_ListBox1");

Please note that the "RadScheduler1" is the ID of the RadScheduler and "ListBox1" is the ID of the ListBox. However this is not appropriate because ASP.NET ListBox has no client-side API.

I suggest you to subscribe to the OnFormCreated server-side event and find the ListBox via e.Container.FindControl as the datePicker is found in this help article.
