ASP.NET Calendar Control Weird

OK I'm using .NET 1.1 with a calendar control.  When I put the calendar control on an .aspx it works just fine.  When I bring the calendar (exact same function in the code behind) to a user control it no longer works.  It gives me a javascript error: "Object expected".  Any idea what is going on?  Is my user control not passing the event up to the page level?

when you bring the calendar control to a user control, the id of the calendar control at client side is changed as UserControlID_CalendarControlId, so if you refer to the calendar id at client side, it will cause an "object expected" error.

that's 1 possibilitym, send your code.

here is the control code (I am using a basepage):

<form runat="server" ID="Form1" method="post">
      <table border="0" cellpadding="0" cellspacing="0">
            <tr>
                  <td valign="top" style="HEIGHT: 16px">
                        <asp:TextBox id="txtDate" runat="server" Width="100px"></asp:TextBox>
                  </td>
                  <td valign="top" style="HEIGHT: 16px">
                        <asp:Button id="btnSelect" runat="server" Text="Select"></asp:Button>
                  </td>
            </tr>
            <tr>
                  <td valign="top" colspan="2">
                        <asp:Calendar id="calDate" runat="server" Width="160px" BackColor="White"
DayNameFormat="FirstLetter" ForeColor="Black" Height="180px" Font-Size="8pt" Font-Names="Verdana" BorderColor="#999999"CellPadding="4" Visible="True" onselectionchanged="calDate_SelectionChanged"></asp:Calendar>
                  </td>
            </tr>
      </table>
</form>
<P></P>

And here is the code behind for the control:
 Protected Sub calDate_SelectionChanged(ByVal sender As Object, ByVal e As EventArgs)
        Dim dtDate As System.DateTime = calDate.SelectedDate
        txtDate.Text = dtDate.ToShortDateString()
    End Sub


And here is the page (again I am using a basepage):
<%@ Register tagprefix="body" tagname="body" src="calControl.ascx" %>
      <body:body runat="Server" ID="body" NAME="body" />

Thanks!!

I get the error when I click on a date.  The page loads fine and displays the calendar.  It just doesn't work when I click on a date on the calendar.

Thanks!!

add a try / catch block around that method... what's the runtime error?

i just recreated your control, put it in a web page, and it works fine.

Protected Sub calDate_SelectionChanged(ByVal sender As Object, ByVal e As EventArgs)
      Try
            Dim dtDate As System.DateTime = calDate.SelectedDate
            txtDate.Text = dtDate.ToShortDateString()
      Catch ex as Exception
            Response.Write(ex.ToString());
      End Try
End Sub

I've tried putting a breakpoint on the code, but the client side never gets to call it because it screams about the javascript error: "Object Unidentified"

sounds like you don't have the javascript files there.

for the default installation of iis you should see the following (assuming .net 1.1):
C:\Inetpub\wwwroot\aspnet_client\system_web\1_1_4322

this should have three files in it:
SmartNav.htm
SmartNav.js
WebUIValidation.js

in this instance, the SmartNav.js is the file it's looking for.

cause you use BasePage, so i might cause the problem. How about try to debug javascript with VS.NET. Try to turn on JavaScript debuging in IE's options (Tools\Options)...

I think the __doPostBack function doesnot exist in the page.

It was the base page issue -- I just moved the code up to the page level and everything was fixed.  Thanks for the help!!
