Hi Glenn,

Thanks for your response.

Pl find attached my solution. I'v overridden GetData method to pull data from google calendar instead of database. Similarly I'm trying to save in google calendar in Insert method. When testing this, pl don't forget to change google account details at respective places (search for @gmail.com).

The null parameter is caused because the insert parameter in the IS DataSource does not match the field which already bound in the EventBinding WebScheduler property.

Here is the EventBinding property in your WebScheduler attached project:

<EventsBinding AllDayEventField="AllDayEvent" CategoryIDField="CategoryID" DescriptionField="Description"
    EndTimeField="EndTime" EventIDField="ID" LocationField="Location" ModeField="Mode"
    ReminderTimeSpanField="Reminder" ResourceIDField="ResourceID" StartTimeField="StartTime"
    SubjectField="Subject" />

The correct insert parameter in the IS DataSource table Events:

<InsertParameters>
    <asp:Parameter Name="ID" Type="Int32" />
    <asp:Parameter Name="CategoryID" Type="String" />
    <asp:Parameter Name="ResourceID" Type="Int32" />
    <asp:Parameter Name="Mode" Type="Int32" />
    <asp:Parameter Name="Subject" Type="String" />
    <asp:Parameter Name="Description" Type="String" />
    <asp:Parameter Name="Location" Type="String" />
    <asp:Parameter Name="AllDayEvent" Type="Boolean" />
    <asp:Parameter Name="StartTime" Type="DateTime" />
    <asp:Parameter Name="EndTime" Type="DateTime" />
    <asp:Parameter Name="ReminderTimeSpan" Type="Int32" />
</InsertParameters>
