It appears like something is stopping my errors from displaying normally an in ASP.NET site.
Scenario 1 - I have an admin screen that has most of its content inside an updatepanel. When the user's session times out. You click a button and nothing happens. It doesn't redirect you to the home page and it doesn't give you an error message.
Scenario 2 - I have some sort of data issue throwing an error - its happening on the staging environment otherwise I'd just debug the code normally. But instead of showing me the error you get the javascript type exclamation mark down the bottom and you need to quickly click on it to bring up a pop up dialog. In IE this happens. In FF there is no error message at all being shown.
My error in this instance is Sys.WebForms.PageRequestManagerServerErrorException: Sequence contains no elements. It then refers to a ScriptResource.axd... so based on this error message I'm having trouble working out what the problem is as I can't reproduce this on my dev environment. I believe its usually related to a linq statement referencing something with no elements but am not sure where the error is occurring or why. But am also wondering why this error appears to be being caught and not displayed look good old fashioned exceptions :)
So not sure if its an updatepanel issue or a scriptmanager related quirk. I imagine I'm using the wrong keywords to google as I can't find anyone else really complaining about the same thing.
I am new in ASP.net and working with 4.0 framework. My problem is that when i paste all page with directory into local iis configured directory inetputwwwroot , and try to run it with
browser http://localhost/webpage1/default.aspx/
it gives an error message
"The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.
A name was started with an invalid character. Error processing resource 'file:///C:/inetpub/wwwroot/WebSite3/Default.aspx'....
I have a requirement that one of multiple fields is required. Using custom validator the even fires, false is returned, but no error message is display and the form validates. What am I missing? I have tried with and without ValidationSummary.
I've placed Html.ValidationSummary(true) on my page so that an error can be displayed that are not associated with a field.
This renders the following html <div class="validation-summary-errors"><ul><li style="display: none;"></li> when there are some ModelState errors are present, all of which are associated with a field. ie there are no page level errors
I've put some background and border styles on the div which give the look that I want.
The problem is that the div is visible even though the collection is empty.
I understand why this is happening but was wonder if there where any techniches to prevent the html from being rendered or to hide the div using styles if the ModelState errors collection is empty?
If its possible I'd like to avoid using jquery to hide the validation summary as the site should work without javascript.
Recently I have upgraded my app from .net 2.0 to 4.0. By running application under .net 4.0 I get one strange behaviour. Whenever application throw any error, instead of displaying it in browser with call stack, the error is shown in the browser's error window as javascript error and the whole web page remain as it is. is it feature of .net 4.0 or I need to do some settings to display error in web page.
i have genarated a xml file through the asp.net code as
public bool createxml() { DataSet ds = new DataSet(); clsRegister obj = new clsRegister(); int i = 0; string strpath = string.Empty; XmlTextWriter objwriter = new XmlTextWriter(Console.Out); ds = obj.searchgallery(4); try { strpath = "d:\hellojhasi\glance\jhansigallery\gallery.xml"; objwriter = new XmlTextWriter(strpath, System.Text.Encoding.Default); if (ds.Tables[0].Rows.Count > 0) { for (i = 0; i < ds.Tables[0].Rows.Count; i++) { objwriter.WriteStartElement("picturegallery"); objwriter.WriteElementString("fullimage", ds.Tables[0].Rows[i]["fullimage"].ToString()); objwriter.WriteElementString("thumbnail", ds.Tables[0].Rows[i]["thumbnail"].ToString()); objwriter.WriteElementString("title", ds.Tables[0].Rows[i]["title"].ToString()); objwriter.WriteElementString("description", ds.Tables[0].Rows[i]["description"].ToString()); objwriter.WriteElementString("height", ds.Tables[0].Rows[i]["height"].ToString()); objwriter.WriteElementString("width", ds.Tables[0].Rows[i]["width"].ToString()); objwriter.WriteEndElement(); } } else { objwriter.WriteEndElement(); } objwriter.Flush(); } catch (Exception e) { } return true; }
the code executed well.but the xml file when opens gives the following error

I've got a Varchar2 field in my table which I want to convert to a CLOB. I am unsure whether the data would get truncated when selected. If so, what is the limit and does it depend on the database settings?
In my TOAD or SQLPLUS window it gets truncated but this may just be the environment settings. I'm not sure whether it would get truncated in my actual application (I can test this, but up to what size should I test?)
If it does get truncated, what's the best way to display the whole CLOB? There are other fields in my SELECT query, so I think I can't just loop through multiple rows. Is there any way out?
I have set executionTimeout in web.config to 3600 (which I found out that the scripttimeout will follow this value), and in the production server, I have set debug=false, session time out = 20 min. sql command time out = 1200 seconds
However, when the application is performing heavy sql task that exceed 90seconds, I got the 'Page Could Not be Displayed' error.
When I change debug=true, the application works fine. The application also works fine when I turn off the 'Show HTTP friendly message'.
I am using VWD 2010 beta 2 and Ajax toolkit 3.031106, the problem is mainly the calendar extender.I have the controls in my new tab but cant drag the calendar extender (just get the crossed black circle cursor). Some control I can drag down other not and none of them shows when I look at the page in my browser.there are no errors displayed at all.
I have a site written for ASP.NET using a library written for ASP. The library resides in a dll and the site calls it to get the number of leave days an employee has left from a database. The dll was outsourced so I don't have access to the source.
I've set up the database and visual studio project locally. When I run the site and login to the system, an error message is displayed where the leave days should be displayed but the site runs normally. If I register the dll using regsvr32, the leave days are displayed when I login, but when I try to browse the rest of the site, the session is dropped and I'm automagically logged out. If I deregister the dll, then I can browse the site once I've logged in again but, once again, the error is displayed.

Today I was sending some messages to my friends on Facebook. My friend by accident plug-out my network cable and I didn't see my connection lost. When I tried to send my message, Facebook gave me a little error on message sendin window, but Facebook was looking very good as when my connection online. When connection losts during form or data sending/receiving process on my Asp.NET web sites. Standart "Page can not be displayed. Try again." page shows up. How can we do it like facebook?
I worked with updatepanel with visual studio.net 2005 and it was working fine but after using visual studio.net 2010 I get error message when I try to use updatepanel control. here is what I get:
Parser Error Message: Type 'System.Web.UI.UpdatePanel' does not have a public property named 'CreateUserWizard'. Source Error: Line 9: <asp:UpdatePanel ID="UpdatePanel1" runat="server"> Line 10: Line 11: <asp:CreateUserWizard ID="RegisterUser" runat="server" EnableViewState="False" Line 12: oncreateduser="RegisterUser_CreatedUser" DisableCreatedUser="true" Line 13: ContinueDestinationPageUrl="~/Account/ActivationUser.aspx"
anything has changed in visual studio.net 2010 with ajax?
I am trying to register below mentioned javascript for using with GridView to add freeze functioality on GridView. When compiling an error is thrown Microsoft JScript runtime error: 'Sys' is undefined
How it can be fixed.
<script language="javascript" type="text/javascript"> // This Script is used to maintain Grid Scroll on Partial Postback var scrollTop; //Register Begin Request and End Request Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); //Get The Div Scroll Position function BeginRequestHandler(sender, args) { var m = document.getElementById('divGrid'); scrollTop=m.scrollTop; } //Set The Div Scroll Position function EndRequestHandler(sender, args) { var m = document.getElementById('divGrid'); m.scrollTop = scrollTop; } </script>
I use an updatepanel and I register a handler for endRequest to catch errors: Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); On the server an exception is thrown to test the client side. The problem is that in IE and FireFox EndRequestHandler is never called! It works as expected in Opera and Safari. On a simple page with few controls it works as expected in all browsers. What I found out with Firebug is that the response is Content-length: 67, but there is no response (empty tab for response)! The expected response is 53|error|500|Object reference not set to an instance of an object.|
I have not debugged the ajax library precisely but what I have seen is that some code runs to prepare for pageLoading event (maybe because it cannot detect the error?), but there is no information for updatepanels from the response and an error occurs trying to use an object for updatepanels which is null. The error is caught by a try-finally block.
I been stack for the last few days trying to figure out the SilverLight 4 LineSeries graph, for some strange reason the graph being displayed but the line not being displayed. I am pretty sure that my mistake is something very basic but I been straggling to pinpoint the problem by myself.Bellow is the code that I having problem with.
I have two update panels and one javascript control.
When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.
However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.
i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.
I am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
