.NET Forum / ASP.NET / General / April 2008UpdatePanel.Update() doesn't work in Firefox
I have an update panel that has the UpdateMode set to "Conditional". When I call UpdatePanel1.Update() in the VB code it does not work in FireFox. It works just fine in Internet Explorer 6.0. Any ideas on how to fix it so it works in FireFox 2.0.0.14? Because the updatepanel runs on the client and renders part of the page without calling the server, I'm assuming that the script manager that it runs on is implemented as a Microsoft behavior. Firefox, Netscape, Mozilla, IE4 and earlier do not support Microsoft behaviors. You can test if this is the problem by trying to run your stuff on these other browsers. If it is because of behaviors, then your app won't work on these either. W3C has another HTML extensibility model equivalent to MS behaviors called Actions. To get your stuff to work on Netscape based browsers, you will have to re-implement the script manager and update panel controls as Actions (or see if somebody else has already done that). > Because the updatepanel runs on the client and renders part of the > page without calling the server, I'm assuming that the script manager [quoted text clipped - 8 lines] > you will have to re-implement the script manager and update panel > controls as Actions (or see if somebody else has already done that). Anyone know anything about implementing the update panel as Actions? forget about this actions malarky - can you post an example that demonstrates the issue ? >> Because the updatepanel runs on the client and renders part of the >> page without calling the server, I'm assuming that the script manager [quoted text clipped - 10 lines] > > Anyone know anything about implementing the update panel as Actions? for example , this works just fine in ie/ff/opera/... ===== WebForm1.aspx ======= <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Web.WebForm1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="ScriptManager1" runat="server" /> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> 1 <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:Button ID="Button1" runat="server" Text="Just 1" onclick="Button1_Click" /> <asp:Button ID="Button3" runat="server" onclick="Button3_Click" Text="Both" /> </ContentTemplate> </asp:UpdatePanel> <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional"> <ContentTemplate> 2 <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox> <asp:Button ID="Button2" runat="server" Text="Just 2" onclick="Button2_Click" /> </ContentTemplate> </asp:UpdatePanel> </div> </form> </body> </html> ====== WebForm1.aspx.cs ========= using System; namespace Web { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load( object sender , EventArgs e ) { } private void UpdateThings() { TextBox1.Text = TextBox2.Text = DateTime.Now.ToString( "hh:mm:ss.ffffff" ); } protected void Button1_Click( object sender , EventArgs e ) { UpdateThings(); } protected void Button3_Click( object sender , EventArgs e ) { UpdateThings(); UpdatePanel2.Update(); } protected void Button2_Click( object sender , EventArgs e ) { UpdateThings(); } } } > forget about this actions malarky - can you post an example that > demonstrates the issue ?

Fixed. Apparently this is a known issue with images in UpdatePanels. I "change" the imageURL of the imagebutton to something different each time, by appending "?a=" followed by a number which gets incremented each time. Now the image updates properly. most likely you have a scripting error on the page that prevents the ajax call. install firebug in ff and see what your error is. .Update is a server sde method, so if it is firing with ff, then you have a serverside error, as this means the ajax library is running. -- bruce (sqlwork.com) > I have an update panel that has the UpdateMode set to "Conditional". > When I call UpdatePanel1.Update() in the VB code it does not work in > FireFox.
