    Hi there,

    I am attempting to populate a combo box within a panel when the RadScheduler form Creating method is called.

    if i walk through the code i can see the process hitting the breakpoint however when the combo box is displayed it is blank.

        Protected Sub RadScheduler1_FormCreating(ByVal sender As Object, ByVal e As SchedulerFormCreatingEventArgs)

            If e.Mode = SchedulerFormMode.Insert Then

                e.Cancel = True

            ElseIf e.Mode = SchedulerFormMode.Edit Then

                e.Cancel = True

                ScriptManager.RegisterStartupScript(Page, [GetType](), "formScript", "Sys.Application.add_load(openForm);", True)


                formRSUpdate_tbMessage.Text = "This doesnt get set either!"

            End If

        End Sub

        Private Sub PopulateEditForm()


        End Sub

    Within my aspx i have the following...

    <telerik:RadDock runat="server" ID="RadDock1" Width="350px" Height="220px" Closed="true" Style="z-index: 2000;" Title="Edit Appointment">





    <asp:Panel ID="PanelDock" runat="server">



    <td style="text-align: left">

        <telerik:RadComboBox ID="formRSUpdate_ComboBox1" runat="server" AutoPostBack="True" Width="220px" />


    The auto postback is set to true because this is the first of two cascading combo boxes.

    The selection within this combo box drives the population of the second.

    If i use a sqldatasource, I can populate Combox1, and combox2 successfully populates.

    However since i need to drive both on the specific appointment i would like to keep

    everything within the code behind.

    This also does not get set.

    formRSUpdate_tbMessage.Text = "This doesn't get set either!"

    Can you please help?  I am trying to populate a bunch of controls within the form from the appointment.

    I tried to replicate the faced issue, base on the provided code snippets and information, but to no avail. I noticed that you are populating the RadComboBox using - ComboUtils.FillComboBox1(formRSUpdate_ComboBox1). Could you demonstrate us the logic and code in the Class? In addition, I am sending you a sample project, base on the provided code snippets, demonstrating the correct population with data of the RadComboBox.
