Ajax calls within <table> tag causing error.
htmlfile: Unknown runtime error
I am pasting here full code to produce error. Please help me to sort it out.This is my code for .aspx file. Paste it in new .aspx file inside form tag.
[Code].... And this is code behind file code. Paste it inside .aspx.cs public partial class.
[Code]....
I can't figure out why I might be getting this error. It happens on an ajax call.This is the full error text:

If a user enters "<" or if it already exists in a textbox inside an update panel, I am getting "internal server error 500" during post back. I believe the page suspects a HTML injection and is attempting to stop it. I could use Page.EnableEventValidation to avoid it but I really don't want to do that. Is there any other way, I could resolve it (like replace < with > or something like that)?
Update:
This is happening in a textbox inside a gridView.
[Code]....
I have a table with 3 rows, each with an ASP.NET panel with a gridview in it. For some reason, this is causing IE8 to go into compatibility view mode. If I change the table to 3 seperate divs, this works but if I use divs some functionality (i.e. max height) doesn't work as it does on tables. I've also tried 3 seperate tables but to no avail.
View 2 RepliesI'm trying to use a master page in my website. I created a page and then created the master. I then added the tag MasterPageFile="~/master". I'm guessing that I need to do something to my main page, because I've now started getting the error:
The page contains markup that is not valid when attached to a master page
My main page is as follows:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" MasterPageFile="~/my.master" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>
<form id="form1" runat="server">
<div>
</div>
</form>
</body>
</html>
I tried deleting the tag thinking that this might be the issue. Can anyone point me in the right direction?
I am trying to connect to a database on my local server. The database is called "dbtest." Of course, I have left off my actual password and replaced it with "password."
This is the typical code I see on every tutorial, but it doesn't work at all. Please help.
<%
Dim con, rs
con = Server.CreateObject("ADODB.Connection") 'I think it is something to do with this line
con.Open "Provider=sqloledb;SERVER=localhost;DATABASE=dbtest;UID=administrator; PWD=password;"
rs = Server.CreateObject("ADODB.Recordset")

I have the following Page_Load function...
protected void Page_Load(object sender, EventArgs e)
{
XmlDataSource1.Data = GetXmlFromFile(Request.QueryString["file"]);
XmlDataSource1.DataBind();
Repeater1.DataBind();
}
The page in which this Page_Load resides is called by a parent page. Each time this Page_Load gets called the value of "file" in the query string will be different. So each time I will be receiving the XML contents from a different file which are inserted into the XmlDataSource and then bound against by the Repeater. Getting the XML data from the file works great but when I bind against the repeater that only works the first time through Page_Load. Each time after that when this code is executed the same results from the first XML file are displayed in the repeater.
What am I missing here. How can I get the XML data to be bound against the repeater on each page load instead of just the first one?
I have a webservice (ASP.NET) deployed on a webfarm. A client application consumes it on daily basis. The problem is that some of its calls are duplicated (with difference of milliseconds). For example I have a function Foo(string a,string b). The client app calls this webmethod as Foo('test1','test2') once but my log shows that it is being called twice or sometimes 3 or 4 times randomly. Is this anything wrong with the webfarm or the code? Note that the webmethod has simple straighfarward insert and update statements.

View 4 RepliesIn my ASP.Net page, I allow users to download files from the server. If the file is of even a moderate size (does it with a 40 meg file, for example), when downloading, it fails with the error message:
"Insufficient system resources exist to complete the requested service".
I've checked out the server, and it's quiet (CPU, RAM, Hard Drive, Task Manager Processes, etc all very low in their numbers).
I've run the code from several client machines and I'm getting this error message no matter where I run it from.
A developer has created a custom control in ASP.NET using VB.NET. The custom control uses a repeater. In certain scenarios, the rpt_ItemDataBound event is encountering a data error. My goal is rather than having the user see the yellow screen of death, give the user a friendlier error explaining exactly what the data error is. I figured I would be able to use a Try/Catch block as shown below throw the exception, however, it appears that the event has nowhere to be thrown to and stops executing at the "End Try" line.
Protected Sub rpt_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rpt1.ItemDataBound, rpt2.ItemDataBound
Try
ProcessBadData...
Catch ex As Exception
Throw ex
End Try
End Sub
In VB.NET, I can find where the repeater's DataSource is being set, however, I can not find a DataBind event. how I can capture the exception in this ASCX control so I can report it to the user? Edit: The stack trace looks like this. There is another repeater within the repeater that is actually causing the error (rptOther) and I'm able to catch the error, but I can only throw it to the rpt_ItemDataBound. I can't figure out how rpt_ItemDataBound is getting called without a DataBind event.

So I am getting the following error in firebug regarding jQuery UI. It would be as simple if it was a matter of a process-of-elimination on the JS on the page, but there is allot of JS as well as some on the page and some on the site.master.
ERROR
(this.uiDialogTitlebarCloseText = c("<span/>"))
.addClass("ui-icon ui-icon-closethick").text(m.closeText).appendTo
is not a function
Is there a way in Firebug to see what javascript is the initial caller?
I'm trying to send a string of XML as part of the query string. Normally I'd POST this XML but I'm sending it to a 3rd party system that I can't POST stuff to. So, as it goes, I need the 3rd party system to request the services of one of the pages in my system. (explanation: the 3rd party system produces PDFs of my web pages. I give it a URL to my page, and it PDF's that page. So, the XML file contains data that I need to generate the page) Anyway, I'm getting my query string as follows:
string data = Server.UrlEncode(xmlSnippet.ToString());
string sFullUrl = urlString + "?data=" + data;
I give the 3rd pary system this URL, and it calls my page.. except the request doesn't reach the page. It's failing into the Application_Error handler with this message:
"A potentially dangerous Request.QueryString value was detected from the client (data=[my XML data])" As I know the data I'm sending is safe, is there any way I can make this work?

To find out when there are any exceptions when users are using the system, then the ErrorDetails are being auto-emailed to members on the IT team to help in troubleshooting.

I have an asp.net web page which works with a database. When I first upload it I never disposed the connections so after using the different modules of the application for sometime it would suddenly stop working saying the connection pool filled or something like that.To fix it when a user clicked a button I opened the connection, tell the database what I needed and finally disposed the connection.
This seemed to fix everything, in fact you can work with application all you want, the problem comes if you stop using it for certain time.So for instance, I have a module in my webpage where user can capture information for a certain product. When the user clicks in one button the info gets into the database. If the user is continuosly capturing data everything works fine, but if it goes for about 10 min when he clicks the button he will receive an error. To fix this the user has to log-in again.
Every module opens a connection to the database to verify the user identity, but then after it verifies it I dispose the connection so I don't think there is a problem.
i'm having a serious problem when i' trying to use "HttpContext.Current".
What i' trying to do is to get a querystring value by:
"HttpContext.Current.Request.QueryString["..."]" (in my page base class)
But i got this error:
"Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack"
What could be causing this problem?

I have a complicated join between a few tables but I have managed to replicate the error using linqpad and the small tables below. There are references between the COLNAME column and the YAXIS column and also between COLNAME and XAXIS that is not explicitly defined.
The error is "Specified cast is not valid", which originally I wasted time thinking the problem was converting the data returned to my object in VS 2010, but the error also happens in linqpad with no defined object. It seems insane that a bit column would cause this problem. If I change the column type to a VARCHAR it works fine. If I run the generated SQL from linqpad or sql profiler that also returns fine.

I am having an issue when trying to update a ModifiedDateColumn in the database via LINQ. I am setting the ModifiedDate property (which is a DateTime in both SQL Server and my code) using DateTime.Now. I am getting an error where LINQ is generating too many precisions when generating the SQL to execute. Here is what the LINQ is generating (see @p3 & @p5)

How do I get LINQ to only generate to only 3 decimal places?
I have a dropdown list where the user can select a name, on change event populates a Session variable and at the same time populates a formview with the full record detail. I want to add a List Item that states "Select Name" but when I add this the page errors. Input string was not in a correct format.
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.
Exception Details:
System.FormatException: Input string was not in a correct format.
Because the value returned from the dropdown list box is a string and not a numeric equal to the first name in the list.
AppendDataBoundItems is = true
AutoPostBack is = true
because I want to update the page as a differnent name is selected. I guess I need to not load the form until an actual first name is selected. Uncertain how to prevent the Formview from loading at page load an until a name is selected and not when the dropdown is set back to "Select Name"
I have been tasked with implementing a strategy to catch all errors in an ASP.net application which cause a user request or interaction to crash and then e-mailk this exception to a support team in advance of a user calling about the error.Some errors however are not causing the page to crash or be redirected to the custom error page but these are being emailed to the support team instead of simply being loggedMy requirement is to seperate what exception types will cause a page fail and which will not.Example I am currently receiving a System.Web.HttpUnHandledException which is not causing any page to fall over and therefore is not of relevance to the support team. this can be logged but does not require emailing.

Ran into a bit of problem when using PageMethods when calling a webmethod in the code-behind. My markup page has a radgrid which gets populated via the objectdatasource.Pagemethods works and returns data as expected when the objectdatasource binds the radgrid with some data but not when the objectdatasource returns nothing, i.e. radgrid is empty. PageMethods call has got nothing to do with the objectdatasource, I'm simply using its output to build a list of checkboxes dynamically on the client side using Javascript. And this is how my code snippets looks like:Markup page:
