MasterPageFile Causing Error?

Aug 12, 2010

I'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">
<html xmlns="http://www.w3.org/1999/xhtml">
<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?

Downloading File Process Causing Error?

Mar 11, 2010

In 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.

Event Causing Error But Can't Catch Exception

Apr 22, 2010

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.

Javascript Is Causing JQuery UI Error In Firebug?

Mar 29, 2011

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?

C# - Send Server.UrlEncoded XML In Querystring Causing Error?

Apr 23, 2010

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?

SQL Server :: Connection To Database Expires Causing An Error?

Aug 9, 2010

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.

Web Forms :: Set The MasterPageFile Of A MasterPage?

Jan 21, 2011

I have a Page (index.aspx) that inherits from MasterPage (Index.Master) that inherits from another MasterPage (/template1/Website.Master). I want to be able to set the masterpagefile of Index.Master to /template2/Website.Master programmatically.

My index.aspx is basically a placeholder file (I have multiple directories with the same placeholder files, and I don't want to have to update every folder if i make a change to 1 file). All the website content is located in Index.Master. The layout of the website is in Website.Master. I want to be able to change the layout based on a selection stored in a local xml file in each of the folders.

I understand I can change the Page PreInit on the aspx page easy enough, but I don't want to change that. It has to link to the index.master.

Index.Master doesn't have a PreInit because it's a masterpage, not a page...

AJAX :: Greater Than Symbol Causing Internal Server Error 500?

Feb 8, 2011

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.

C# - LINQ Union With BIT Column Causing Specified Cast Is Not Valid Error?

Mar 8, 2011

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.

DataSource Controls :: Dropdown List Causing Error When AppendDataBoundItems Is True

Jul 22, 2010

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"

C# - Override Strongly Typed @page Masterpagefile?

Aug 17, 2010

I am working with a third party asp.net application that uses master pages and nested master pages. My needs are to dynamically set the master page files for each page(.aspx). The application by default sets the master page file in the strongly typed @Page directive for each page. I don't want to change the strongly typed directive on each page (over 50 pages) because I am lazy and I want to minimize conflicts with future upgrades.

protected override void OnPreInit(EventArgs e)
{
this.MasterPageFile = "~/MasterPages/MyMaster.master";

Configuration :: Error Handling Strategy For Exceptions Causing Page Request Fail?

Nov 1, 2010

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.

For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.

HttpHandlers / Modules :: URL Rewriter Causing A "500 Internal Server Error"

Apr 1, 2011

I've set up URL Rewriting per Scott Guthrie's guidance (Scott's blog - Approach 3: Using an HTTP module to perform extension-less url rewriting with IIS7) and I'm using Url Rewriter.

OK, so it was a piece of cake to setup and everything runs perfectly on the dev server (cassini). I was all excited and put it on the production server and it immediately choked - the site won't even load and instead gives a "500 internal server error"

Production server is a shared hosting environment running IIS 7 in integrated mode , ASP.net 3.5 and SSL.

I have another HTTP module installed called Security Switch , which I disabled to remove it from the equation. I don't think that affects anything since it was already running fine on the dev server and prod server, but I'm not 100% sure and wanted to throw it out there if that helps diagnose.

I've followed the setup instructions precisely, triple checked everything in web.config and I can't figure out what I'm doing wrong. I'm guessing it must be getting stuck in the IIS 7 pipeline somewhere. Can the SSL have something to do with it?
