Hi friends

I have the same problem with IE 8 and Anthem.NET ajax library

Unfortunately i could not solve the problem with this solution but i have another solution for this problem :

just use a LinkButton with Image control inside instead of ImageButton like this :

<asp:LinkButton ID="btnRemove" runat="server" CommandArgument='<%# Eval("DemandID") %>' CommandName="delete"
<asp:Image runat="server" ImageUrl="~/Icons/Small/remove.png" ID="imgDelete" />
</asp:LinkButton>

I HOPE they fix this problem in the next build. Any place else I can post this bug?

kashif, I was tracing the error in the event log and catching exceptions, that's why I choose to "clear" the error (check the other thread), because I "know' that this specific error would hurt the application:
I'd just like to remark that it only happens when you click over an image to trigger an async post back:

Here is the trace for one of them:

Event Type:    Error
Event Source:    ASP.NET 2.0.50727.0
Event Category:    None
Event ID:    1078
Date:        10/11/2006
Time:        12:46:16
User:        N/A
Computer:    JUAN01
Description:
The state server has closed an expired TCP/IP connection. The IP address of the client is 127.0.0.1. The expired Read operation began at 11/10/2006 12:45:53.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

And, here is the "cleaning" code:

Code behind:

   Protected Sub ScriptManager1_AsyncPostBackError(ByVal sender As Object, ByVal e As Microsoft.Web.UI.AsyncPostBackErrorEventArgs) Handles ScriptManager1.AsyncPostBackError
      If e.Exception.Message = "Input string was not in a correct format." Then
         Server.ClearError()
      Else
         ScriptManager1.AsyncPostBackErrorMessage = e.Exception.Message
      End If
   End Sub

Page code:

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true"
            ScriptMode="Release" />

        <script type="text/javascript">
        Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
            function EndRequestHandler(sender, args)
            {
                if (args.get_error() != undefined && args.get_error().httpStatusCode == '500')
                {
                var errorMessage = args.get_error().message;
                args.set_errorHandled(true);
                }
            }
        </script>

I hope this helps,

Juan

I had initially mistaken it to be a parse error on the client and thus wanted to look at the server response. Seems like the error is happening on the server itself. Can you handle errors to redirect to a custom error page and log the stack trace of the exception [use Server.GetLastError() in Application_onError from global.asax] to see where exactly this error happens in the code - whether it is your code or framework code running on the stack when this error is encountered. Alternatively, you can debug to catch all exceptions and break into the error to see the code that is failing. Thanks!

I'm experienging the same problem. There is another thread about it: http://forums.asp.net/thread/1457827.aspx

And, I reproduced it again and here is the Fiddler trace:

HTTP/1.1 200 OK
Server: ASP.NET Development Server/8.0.0.0
Date: Thu, 09 Nov 2006 22:43:40 GMT
X-AspNet-Version: 2.0.50727
Cache-Control: private
Content-Type: text/html; charset=utf-8
Content-Length: 55
Connection: Close

41|error|500|Input string was not in a correct format.|

I don't know if this information is enough, I can post more Fiddler details and/or my code if needed.
In the other thread I mentioned there is a proposed workaround.

Cheers,

Juan

Could you please use the fiddler tool, capture the trace when this error happens and post it to this thread? Thanks!

Can you wrap the databinding logic for the repeater in a !IsPostBack construct [add

If (Not IsPostBack) Then

...

End If

around your code, it's not good coding practice to be binding on each post-back], by the way I couldn't reproduce the error using the code you provided above. It would be great if you could use the FiddlerTool and paste the actual output you received on the client when this error occured.

Thanks, Kashif

You have to be using IE 6 or higher. I tried it on 3 computers and it had the bug on every one.

There is no count sometimes it's like 10 sometimes 20 sometimes 5 .... back and forth clicking on the different ones. Very sporadic.

It never happened to me... how many times it should be clicked to get this error?

Code is below. If you click on the image buttons back and forth back and forth. You will eventually get error: Input string was not in a correct format.

<atlas:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />

<div>

<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional" RenderMode="inline">

<asp:Repeater ID="rptMonth" runat="server">

<tr>

<asp:Label ID="lblMonth" runat="server" Text='<%# Container.DataItem %>' Visible="true"></asp:Label></td>

<asp:ImageButton ID="ibtnColor" runat="server" ImageAlign="AbsBottom" ImageUrl="~/collapse.jpg" />

</td>

</tr>

</ItemTemplate>

</asp:Repeater>

</table>

</ContentTemplate>

</atlas:UpdatePanel>

</div>

</form>

Dim interval As Integer = 4

Dim arrMonths As ArrayList = New ArrayList

For i As Integer = 0 To interval

arrMonths.Add(i)

arrMonths.Sort()

rptMonth.DataSource = arrMonths

rptMonth.DataBind()
