master pages and AJAX controls

mike

I'm having a problem getting AJAX working with a master page.

I have created a new website using the AJAXControlTool kit template and
default.aspx as follows.

<%@ Page Language="C#" AutoEventWireup ="true"
CodeFile="Defau lt.aspx.cs" Inherits="_Defa ult" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/
TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitl ed Page</title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptMana ger ID="ScriptManag er1" runat="server" />
<asp:Panel ID="Panel1" runat="server" Height="134px"
Width="217px">
This is where the definition goes! It should be invisible
until the LinkButton is hovered on.

</asp:Panel>
<br />
<asp:LinkButt on ID="LinkButton1 "
runat="server"> LinkButton</asp:LinkButton> <br />
<ajaxToolkit:An imationExtender ID="AnimationEx tender1"
runat="server" TargetControlID ="LinkButton 1">
<Animations>
<OnHoverOver>
<FadeIn AnimationTarget ="Panel1" Duration=".
5" />
</OnHoverOver>
<OnHoverOut>
<FadeOut AnimationTarget ="Panel1" Duration=".
5" />
</OnHoverOut>
</Animations>

</ajaxToolkit:Ani mationExtender>
</form>
</body>
</html>

This page works correctly, fading in when hovering over the LinkButton
and fading out when moving off.

Then I created a master page (I added nothing to it) and a new WebForm
based on this master page.

Here's the WebForm.

<%@ Page Language="C#" MasterPageFile= "~/MasterPage.mast er"
AutoEventWireup ="true" CodeFile="ATKTe st.aspx.cs" Inherits="ATKTe st"
Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHol derID="ContentP laceHolder1"
Runat="Server">
<div>
<asp:ScriptMana ger ID="ScriptManag er1" runat="server" />

<asp:Panel ID="Panel1" runat="server" Height="134px"
Width="217px">
This is where the definition goes! It should be
invisible until the LinkButton is hovered on.

</asp:Panel>
<br />
<asp:LinkButt on ID="LinkButton1 " runat="server"> AM -
Amplitude</asp:LinkButton> <br />
<ajaxToolkit:An imationExtender ID="AnimationEx tender1"
runat="server" TargetControlID ="LinkButton 1">
<Animations>
<OnHoverOver>
<FadeIn AnimationTarget ="Panel1" Duration=".
5" />
</OnHoverOver>
<OnHoverOut>
<FadeOut AnimationTarget ="Panel1" Duration=".
5" />
</OnHoverOut>
</Animations>

</ajaxToolkit:Ani mationExtender>
</div>
</asp:Content>

this page does not work and generates a Javascript error as follows:
----------
Sys.ArgumentExc eption:
AjaxControlTool Kit.Animation.A nimation.set_an imationTarget requires
the ID
of a Sys.UI.DomEleme nt or a Sys.UI.Control. No element or control
could be
found corresponding to 'Panel1'
Parameter name: id
-----------

Any help is greatly appreciated!

you need a form in the master page if you remove it from the page.

The master page has a form tag in it - it is the exact master page
that is created when you select 'New' from the menu and 'Master Page'
from the dialog.

Being a newbie on this myself, I had a table in an updatepanel and
was getting the same/similar error (from memory).

I had to do something in the codebehind in the page_load method like:

if (table1 == null) table1 = new Table()

then I had to add it to the form using

form1.Controls. Add(table1).
Not sure quite why I had to do this, but it seemed to fix the problem.

The error stems from the fact that MasterPages mangle the ID of
controls - Panel1 becomes ctl00_ContentPl aceHolder1_Pane l1 (in my
case).
If I hard code this in, it works fine. Maybe creating the
AnimationExtend er at runtime in PageLoad would allow me to set the
AnimationTarget to the correct ID, which I can find by using
FindControl. I'll play with it and see.

The control's ClientID property will provide the control's decorated
name.The assignment

AnimationExtend er.AnimationTar get = Panel1.ClientID ;

or something similar should work FB

I think there is a UniqueID property.

So something like Panel1.UniqueId .ToString.

I'd have to check tho.
