I think the popup message is a poor idea because OnClientUploadError has already provided developers a good option to handle the error easily in whichever way they prefer. The worst is that if a user clicks OK, he will see a window that should be seen only by software developers. Is there any trick to stop the error alert?

i m Uploading File using Ajax AsyncFileUpload control.. after successful upload i am trying to display success message through Label and Also through Alert but its not working..below is i used code
<asp:Panel ID="pnlupload" runat="server" BackColor="LightBlue"
CssClass="pnlBackGround" Height="100px" style="display:none" Width="600px">
<asp:Label ID="lblmsg" runat="server" Font-Bold="True" Text="" ForeColor="Red"></asp:Label>
<table ID="tabid" runat="server" cellpadding="0" cellspacing="0"
style="border:Solid 2px #D46900; width:100%; height:100%" width="100%">
[code]....
how can i display the message and AsyncFileUpload1
I do have a log system and the correct error is well explicit there, but I want to give a better message to the user.
I keep trying several ways but I'm using Telerik components and well jQuery and I ended up using both ASP.NET Ajax methods and jQuery, so I use
function pageLoad() {
try { [code]....
as well$(document).ready(function() { ... }
that alert(err) is never fired even upon OnClick events
what's the best approach to avoid this message errors and provide a cleaner way?
all this happens in <asp:UpdatePanel> as I use that when I didn't know better (3 years ago!) and I really don't want to mess up and build all again from scratch
Updated with more error windows after volpav solution
I am trying to display an error to the user of a web page using a javascript alert popup, I currently have the following code to clean the error string:
errorMessage.Replace("'", "'")
But this is not sufficient as some illegal characters are not being removed, is there a static method somewhere in the framework that will format my string for clean insertion into html?Update: my initial question was slightly ambiguous. the string needs to be valid as in alert('this is some 'illegal text' that will not popup');I will try Server.HtmlEncode, hopefully it will do the trick.
I receive the error message below, I think because the database field in question is null (I realize I probably should not allow null values, but I can't even display the page to allow the user to enter a value---and I would prefer not to enter a default value in SQL).
How do I avoid this error message? If the column is null (and it is supposed to be an integer), do I need to change the value to something like "0" in the code behind---or is there any easier way to do this right in aspx page (see source of error message below)? Either way, I'm not sure how to do either (I can't get any such lines of code to work here). Object cannot be cast from DBNull to other types.
Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I am a new developer and working on a ASP.Net Site, I am using an Update panel which is updateing the data from SQL database after every few seconds, there is some records in the table for the login user. Now I want to generate a Popup, or Alret Message autometically, every time when update panel is updated, My Update panel has SQLDatasource and gridview its working correctly with timer after every 15 seconds.
But When I am Coding under the Timer Tick the Alret massege is not showing. While I need a notification alret also with every trip of update panel if there is something avilable in the data tabel. I am using Code in Timer Tick: ra is getting from function return value if the table has some records. if(ra>1) response.write("<Script> alert ('something')<Script>); but its not working

If I use the AsyncFileUpload control and I test the page local with VS2010, I get for files above 3.8 Mb an No Access Error.If I go to the AJAX control test page and try to upload a file larger then 3.8, there is no problem.I just installed VS2010

My users are confused by this message, because it shows after they succesfully uploaded a file.

I have got an error "server response error : Unknown server error" while uploading file using Ajax AsyncFileUpload, code behind function is triggered while uploading, but after code behind function executed, we are getting this error.
View 1 RepliesWhen the user tries to upload a file with a size more than 4 MB, the AsyncFileUpload control gives a Confirmation alert (with "OK"/"Cancel" button) with the following message "Server Response error: Maximum Request Lengh Exceeded". But when the User clicks the "OK" button a new window popups and shows the server error and on clicking the cancel button the AsyncFileUpload background color turns red. Here I am not sure why the control is showing a Confirmation alert instead of a simple alert message. Is it possible to change the Confirmation alert with the simple alert message? Basically I don't want the popup window to show the server error as it is happening currently. Also, is there a better way to handle the file size error and show apporiate error message to the users?

View 3 RepliesI produce a popup window by adding a hyperlink to a table cell dynamically in my vb.net code behind. Here is the code:
Dim sHyperlink As
String =
"<a href=""LabPopup.aspx?RefNo=" & iLabRefNo &
""" target=""_blank"">" & strValue &
"</a>" objCellValue.Controls.Add(New LiteralControl(sHyperlink))
So on my web page, I will have a list of these hyperlinks and each have a different iLabRefNo. When I click on one of these links, the popup window does appear correctly.
I have a button on the popup window that closes the popup. But I get this message in an alert box when click on my button:
The webpage you are viewing is trying to close the window. Do you want to close the window?
If I click OK then the window close. But I just want to close the popup wondow without this message. What do I need to do?
Here is my code for the button to close the popup:
<asp:Button
ID="cmdLabPopupClose"
runat="server"
Text="Close"
OnClientClick="CloseWindow()"
/>
<script type="text/javascript">
function CloseWindow() {
window.close();
