Where does the ScriptManager appear in the control tree? You mention in your question that you've added it to the top of the form, but I'm not clear on what you mean by that. You may or may not already be aware, but in order for ASP.NET AJAX components to work, the ScriptManager must be added into the control tree before any controls that use it. Ideally, the ScriptManger should be the first tag following the <form> tag. If your ScriptManager appears after your TabPanel, that could explain the message that you are seeing.
If your ScriptManager is in the proper position, the other thing that occurs to me is that you may have a versioning issue. I've seen a couple of posts that mention this, but this[^] one from the ASP.NET forums explains it best, in my opinion.
Hope that helps.

Thanks for your reply I solve that, problem was: i were calling another dll, i called current one and I compiled it OK.
But i still have same error when i drag TabPanel , I run my app and at runtime i didn't get that error also my controls in TabPanel are not showing, in design time I get that error.
Thanks in help

A couple of things that you may wish to explore:- Did you ever have a pre-release version of ASP.NET AJAX on the development machine? If so, did you uninstall all components of it, including the extensions and toolkit?
- If you create a new solution with only an ASP.NET AJAX project, and add just the ScriptManager and TabPanel to the page, do you still get the error?

I drag ScriptManager without problems but when I drag TabPanel I get this error
"An unhandled exception has occured. A ScriptManager is required on the page to use ASP.NET AJAX Script Components"

I have a forum feature request - every message should have the words "How do I" appended to the beginning and a question mark at the end.
|
|
|
|
|
Wasn't hard, was it?
What exactly do you mean? You want the mouse x,y position? The top left corner of the cell x,y position? or the mouse x,y position relative to the cell?
Each one of those is more complex than the last.

I need the top left corner of the cell x,y position.
When I am "mouseovering" through the cells of the gridview, I am positioning an image at the x,y position of the left top corner of the cell
Thanks
For example: Open link and mouseover the cells of the Case Style column.

Morning people,
This morning's delight is a VS2003 web application that i have opened and upgraded in VS2005. After the upgrade VS told me to convert to web app so I've done that aswell.
When i run the code i get this message:<br />
<br />
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. <br />
<br />
Parser Error Message: Could not load type 'Foo.Global'.<br />
<br />
Source Error: <br />
<br />
<br />
Line 1: <%@ Application CodeBehind="Global.asax.cs" Inherits="Foo.Global"%><br />
<br />
<br />
<br />
Source File: /global.asax Line: 1
I read somewhere that i don't need an inherits in .net 2.0 so i deleted it. It now gets to the login page and this happens:
Parser Error Message: Could not load type 'Foo.logon'.
Now i've read that if i use the App_Code folder for my C# files they should be located OK but i seem to have all sorts of App_* folders to chose from but App_Code isn't one of them.
Thanks for any help you can give

In VS2005 instead of CodeBehind we have CodeFile

Might be to remove the Global.asax and add new one as he has converted it from 3003 to 2005 ?

If theres no App_Code folder just create one, VS will do this when you try to add a new source file to the web site.

Dang, I had exactly the same problem when I first switched from VS2k3/ASP.NET 1.x to SD/ASP.NET 2.0
Too bad I dont remember how I solved it.
Make sure you set in IIS you application to use 2.0 version of ASP.NET - I *think* that was the problem.

If you are using VS2k5 just right click on project and select "New ASP.NET Folder..."->"App_Code". Or something like that

i found a few issues going on here.
I created an App_Code folder and stuck all my c# files in it. The error changed and i still wasn't finding the code i needed.
When i did some searching on the web i found that my files had codebehind and not code file in the <page> section at the start. I've changed them all over and it seems to be working apart from a database permissions error, but that's due to a wrong Username password issue so i'm pretty confident that it's up andrunning reasonably well
Thanks

What do you mean by a scrollbar? How have you built it?
|
|
|
|

I'hv created scroolbar with following code
<body onload="sliderInit();">
<span id="slider" style="position:absolute; overflow-x:hidden; overflow-y:scroll; width:20px; left:35px; top:58px; height:364px;"
onscroll="Scroll(slider);" ></span>
</body>
//this function creates span with vertical scroll bar
function sliderInit() {
for(counter = 0; counter <= 50; counter++)
document.all.slider.innerHTML += " <BR>";
}
//this function is for scrolling
function Scroll(spanObj) {
//do some stuff
}
can u suggest some solution
