Message: [QUOTE="news.microsoft.com, post: 526574"] I am going crazy trying to figure this out, and I am wondering if this is a bug in the ASP.Net 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 RequiredFieldValidator in the FooterTemplate. Doing so causes the following Javascript error: 'Page_Validators' 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:LinkButton CommandName="AddNewRecord" Text="Add Custom Threshold" ID="lnkAddThreshold" Runat="server"/> <asp:RequiredFieldValidator ID="reqDdThresholdUpperAddNew" ControlToValidate="txtDdThresholdUpperAddNew" ErrorMessage="Please enter a value" Display="Dynamic" Visible="True" Runat="server"/> </FooterTemplate> Code Behind snippet: protected void BindGrid() { //Set each grid's datasource and bind to it dgDDThresholdData.DataSource=DataAccess.clsCommonAccess.getDBValues(); dgDDThresholdData.DataBind(); //If we are showing a custom version of the form, then allow editing/adding/deleting of values if(Convert.ToInt32(intThresholdTypeID)==2) { dgDDThresholdData.Columns[6].Visible=true; //show the edit column dgDDThresholdData.Columns[7].Visible=true; //show the delete column dgDDThresholdData.ShowFooter = true; //show the footer (add new record) } else { dgDDThresholdData.Columns[6].Visible=false; //hide the edit column dgDDThresholdData.Columns[7].Visible=false; //hide the delete column dgDDThresholdData.ShowFooter = false; //hide the footer (add new record) } } Any ideas?
