Validator in Footer Causing Javascript Error (with ShowFooter)

[Chris S]

I am going crazy trying to figure this out, and I am wondering if this is a
bug in the ASP.Net 1.1 implementation.

My situation:

I have an ASPX page with 2 different modes:

*Mode 1: Datagrid with no footer
*Mode 2: Datagrid with a footer template containing a textbox and an "Add
Record" command (also has an edit column)

Everything works fine until I put a RequiredFieldVa lidator in the
FooterTemplate. Doing so causes the following Javascript error:
'Page_Validator s' is undefined. I believe this is happening because I am
dynamically showing / hiding the footer in my code-behind, depending on a
selected dropdown value within the page.

Is there a workaround / solution for this?

Footer Template snippet:

<FooterTemplate >
<asp:LinkButt on CommandName="Ad dNewRecord" Text="Add Custom Threshold"
ID="lnkAddThres hold" Runat="server"/>
<asp:RequiredFi eldValidator ID="reqDdThresh oldUpperAddNew"
ControlToValida te="txtDdThresh oldUpperAddNew" ErrorMessage="P lease enter a
value" Display="Dynami c" Visible="True" Runat="server"/>
</FooterTemplate>

Code Behind snippet:

protected void BindGrid()
{
//Set each grid's datasource and bind to it
dgDDThresholdDa ta.DataSource=D ataAccess.clsCo mmonAccess.getD BValues();
dgDDThresholdDa ta.DataBind();

//If we are showing a custom version of the form, then allow
editing/adding/deleting of values
if(Convert.ToIn t32(intThreshol dTypeID)==2)
{
dgDDThresholdDa ta.Columns[6].Visible=true; //show the edit column
dgDDThresholdDa ta.Columns[7].Visible=true; //show the delete column
dgDDThresholdDa ta.ShowFooter = true; //show the footer (add new
record)
}
else
{
dgDDThresholdDa ta.Columns[6].Visible=false; //hide the edit column
dgDDThresholdDa ta.Columns[7].Visible=false; //hide the delete column
dgDDThresholdDa ta.ShowFooter = false; //hide the footer (add new
record)
}
}
Any ideas?
