ShowAdvancedInsertForm fails with an error

[Mika]

A linkbutton should open an AdvancedInsertForm but instead I get:

Error serializing value 'Telerik.Web.UI.Appointment' of type 'Telerik.Web.UI.Appointment.'

Markup:

<asp:LinkButton ID="InsertEvent" runat="server">New Event</asp:LinkButton>

Codebehind:

Protected Sub InsertEvent_Click(ByVal sender As Object, ByVal e As EventArgs) Handles InsertEvent.Click
            RadScheduler1.ShowAdvancedInsertForm(DateTime.Now)
End Sub

More details:
"New Event" linkbutton is in a sidebar like in Google Calendar. Clicking the button fires ShowAdvancedInsertForm(DateTime.Now).

Actually, this works when AdvancedInsertForm or AdvancedEditForm is already open, but not when any of the calendar views is visible. Then I get the above error:
Error serializing value 'Telerik.Web.UI.Appointment' of type 'Telerik.Web.UI.Appointment.'

Advanced Form fields are defined in markup/codebehind inside <telerik:radscheduler> tag. Customized ascx templates are not used.

Is this a bug or do I make some mistake here?

Hi Mika,

Please, excuse us for the late reply. The Click handler is executed too late in the page life-cycle and switching to the advanced form in this moment leaves the control in an incorrect state. We will investigate the issue and we will try to improve our code, so we can support this case.

Meanwhile, adding a call to Rebind should solve the issue:

Protected Sub InsertEvent_Click(ByVal sender As Object, ByVal e As EventArgs)
    RadScheduler1.Rebind()
    RadScheduler1.ShowAdvancedInsertForm(DateTime.Now)
End Sub

Hope this helps.

Hi Tsvetomir,

Rebinding solved the issue. Thanks.
