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)

            PopulateEditForm()

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

        End If

    End Sub


    Private Sub PopulateEditForm()

        ComboUtils.FillComboBox1(formRSUpdate_ComboBox1)

    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">

<Commands>

<telerik:DockCloseCommand></telerik:DockCloseCommand>

</Commands>

<ContentTemplate>

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

...

...

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

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

</td>


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.

Hello,

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.
