Accessing resource collection in AppointmentInsert

[jford]

Hi,

I have a RadScheduler with a custom-templated inline insert form.  I have one resource, called "Type".  ASPX markup below:

<telerik:RadScheduler ID="RadScheduler1" runat="server" AllowDelete="True" AllowEdit="True" AllowInsert="True" DataEndField="EndTime" DataKeyField="VacationID" DataRecurrenceField="RecurrenceRule" DataRecurrenceParentKeyField="RecurrenceParentID" DataSourceID="SqlDataSource1" DataStartField="Start" DataSubjectField="Subject" DayStartTime="09:00:00" HoursPanelTimeFormat="h:mm tt" SelectedDate="2007-11-12" SelectedView="MonthView" WorkDayEndTime="18:00:00" WorkDayStartTime="09:00:00" Height="600px" OnAppointmentCreated="RadScheduler1_AppointmentCreated" OnAppointmentInsert="RadScheduler1_AppointmentInsert">
    <ResourceTypes>
<telerik:ResourceType KeyField="VacationTypeID" Name="Type" TextField="VacationType" ForeignKeyField="AppointmentTypeID" DataSourceID="SqlDataSource3" />
   </ResourceTypes>
<InlineInsertTemplate>
   <asp:TextBox
       ID="TitleTextBox"
       runat="server"
       Text='<%# Bind("Subject") %>'
       Width="90%"
       TextMode="MultiLine"
       Height="20px">
   </asp:TextBox>
<asp:DropDownList
               runat="server"
               ID="TypesList"
               DataValueField="VacationTypeID"
               DataSourceID="SqlDataSource3"
               SelectedValue = '<%# Bind("Type") %>'
               DataTextField="VacationType"
               >
           </asp:DropDownList>

   <asp:LinkButton
       ID="InsertButton"
       runat="server"
       CommandName="Insert">
           Insert
           </asp:LinkButton>&nbsp;
           <asp:LinkButton

    <AppointmentTemplate>
        <%# Eval("Subject") %> (<%# Eval("Type.Text") %>)
    </AppointmentTemplate>
            </telerik:RadScheduler>
            <br />
            <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:razzaConnectionString %>"
                DeleteCommand="DELETE FROM Vacations WHERE (VacationID = @VacationID)" InsertCommand="INSERT INTO Vacations(Subject, Start, EndTime, UserID, RoomID, RecurrenceRule, RecurrenceParentID, AppointmentTypeID) VALUES (@Subject, @Start, @EndTime, @UserID, 1, @RecurrenceRule, @RecurrenceParentID, @AppointmentTypeID)"
                SelectCommand="SELECT Vacations.*, VacationTypes.VacationType as TypeName FROM Vacations INNER JOIN VacationTypes ON VacationTypes.VacationTypeID=Vacations.AppointmentTypeID"

            SelectCommand="SELECT [EmployeeID], [EmployeeName] FROM [Prezza_Employees]"></asp:SqlDataSource>
    <asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:razzaConnectionString %>"
            SelectCommand="SELECT [VacationTypeID], [VacationType] FROM [VacationTypes]"></asp:SqlDataSource>
    </form>

I am using the AppointmentInsert event handler to perform a custom-insert method.  I am having trouble, however, programatically accessing the value of the DropDownList "TypesList", which is bound to my resource "Type", in my inline insert form.  Could you provide me with a code example of how this is done.

Hello James,

You should handle the AppointmentCommand event. You can then access the form container and use FindControl to locate the DropDownList. For example:

protected void RadScheduler1_AppointmentCommand(object sender, Telerik.Web.UI.AppointmentCommandEventArgs e)
{
    if (e.CommandName == "Insert")
    {
        DropDownList typesDropDown = e.Container.FindControl("TypesList") as DropDownList;
        if (typesDropDown != null)
        {
            int vacationTypeId = Convert.ToInt32(typesDropDown.SelectedValue);
            // ...
        }
    }
}

Things get more tricky if you have embedded, say, a CheckBoxList inside a RadMenu.

I can find the RadMenu inside the container but had to hunt down the CheckBoxList:

CheckBoxList cbl = e.Container.FindControl("RadMenu").Controls(0).Controls(0).FindControl("CheckBoxList")
