I have fought a bizarre situation for days. Anytime a certain listview loaded the page went into an infinite loop of reloading. I was finally put the listview on a page with nothing else to see if I could isolate the issue.Even with only the folowing code, it continually looped on load even though it brought in the correct data every time.

Using VS2005, VB code behind, I have a page with two DropDownLists and corresponding CascadingDropDown's. I want to automatically postback when the second DropDownList index changes, therefore I have set its AutoPostBack="true". I have wired up the web services and the lists are getting populated as expected in IE7+, FireFox and Opera, but when I view the page in a WebKit based browsers (Chrome, Safari) the CascadingDropDown appear to load in an infinite loop. I included theWebkit compatibility fix but the issue persists. I've attached a working example below.Anyone know why Webkit browsers are infinitely reloading the cascading dropdownlists? Is there a fix?Source code below:Markup:

I wrote an ASP.NET page that requires HTTP Basic authorization, which I put in the Page_Load function:
void Page_Load(object sender, EventArgs e)
{
string auth = Request.Headers["Authorization"];
if (string.IsNullOrEmpty(auth))
{
Response.StatusCode = 401;
}
else
{
string[] usernameAndPassword = Encoding.UTF8.GetString(Convert.FromBase64String(auth)).Split(':');
string username = usernameAndPassword[0];
string password = usernameAndPassword[1];
Login(username, password);
}
}
When I try to view the page in a browser (either Firefox or IE), it asks me for the username and password, and then...asks me for the username and password again.
Why does this happen, and how can I fix it?
I have an application that works great on localhost with forms authentication.I deployed it to the deployment machine and it to the build machine and received and endless set of 302 redirects.I try logging onto the deployment machine and access the page via the deployment machines ip and it works again.So it is not working when I try and access the site from my computer to the build computer.

I am having problems moving my reports from VS2008 to VS2010. I have made several WEB reports in VS2008 that use the code below on the load event of the WEB page to provide a data for the report and they all work correctly. I have to use this method of providing data because I am using several complicated queries that brake the VS2008 and VS2010 wizard.
When I try to convert over to VS2010, the report loading message flashes on the screen and the report never loads. I have run this code in debug and found that it is causing an infinite loop. After the code runs, the load event fires again. I tried adding an exit sub at the end of the code for a test but it has no effect.Below is a sample of the code that I am using with a simplified query and names.

I am calling a method with __doPostBack using the OnFocus event for the controls. However I need to update the values multiple controls when the server method executes. This actually causes on focus to keep firing. Looking for help. I tried using TextBox1.Attributes.Remove("onfocus") and then adding it the javascript after processing but it still keep looping. Here is a sample using to textbox's for simplicity:

I've found a bug with RC2's client-side validation that causes an infinite loop (at least in IE7).Basically, if you create a standard ASP.NET MVC 2 RC2 web application template and then modify the LogOn.aspx view to this:
[Code]....
Note the new table that has been placed around it.Now, when you fire it up in IE7 and hit "Log On", the whole browser freezes and goes into an infinite loop.I have narrowed this down to the use of OnPropertyChange and the setting of the CSS classes for the elements themselves. It seems whenever an element is in a table, and you change its CSS class, the OnPropertyChange event fires with the property of "value" (which fires the entire process off again hence the endless loop).This is reproducable for me in IE7 (I haven't tested FireFox, IE6 or IE8).
I have a textbox with numeric updown extender.I want the text of the textbox.I have written code in code file is
String a=txtHour.Text
// Source FIle COde
<asp:TextBox ID="txtHour" runat="server" ReadOnly="True" Width="45"
Style="text-align:center" Height="20px">
</asp:TextBox>
<cc1:NumericUpDownExtender ID="NumericUpDownExtenderHr" runat="server"
Enabled="True"
Minimum="00" Maximum="23"
TargetControlID="txtHour" Width="40">

I have error handling in Application_Error event of globals.asax file. Inside this event, I'm using Response.Redirect(~errorview.aspx) method, for redirection to site which is able to handle errors in user friendly way.
Everything works fine, unless exception is rising in Application_Start event. When error occurs there, my application gets trapped in infinite loop with the Application_Error method hit repeatedly. What is more, the page I'm redirecting to never gets hit. Changing Response.Redirect(~errorview.aspx) method to Response.Redirect(~errorview.aspx, false) changes nothing.
The good news is, when Response.Redirect(~errorview.aspx) has been replaced with Server.Transfer(~errorview.aspx), errorview.aspx page succesfully gets hit.
The side effect now is not loading CSS, and errorview.aspx page looks ugly. What is more, the CSS is not loaded only when exception occurs in Application_Start event. Exceptions thrown from any other place don't make the CSS mess.
How I can handle this problem in correct way, and why the CSS is missing in the one particular situation ? What is the appropriate way of handling errors in my case ?
UPDATE
For CSS loading, I'm using this:
<link href="~/Css/Layout/style.css" type="text/css" rel="stylesheet"
runat="server" ID="_uid" />
error page I'm transfering from: http://localhost/APP/Pages/Module/Pages/ErrorView.aspx
css folder path: http://localhost/APP/Pages/Module/CSS/Layout/style.css
I am using ASP.NET 2.0 with VB. In design view of grid, i have one textbox in its template field. I also have one Ajax Calender Extender and FilteredTextBox Extender. I have set target controlId of both calender and filteredtextbox extender equal to that textbox. Now dynamically i dispose one of the extender from that textbox. everything works ok. But once my page reloads it takes the original design image, means both extenders are being set to that textbox.

View 3 RepliesI'm developing my first Facebook application in ASP.NET 2.0 and doing a simplest thing, that is, to show a navigation on top with four hyperlinks where each link targets to another .aspx page. How can I do this using FBML in ASP.NET 2.0?
Otherwise coming to my question, where I'm struck after trying above thing at myself and failed then had to go around the Ajax way of doing this. Now I'm using Ajax call over the onclick event of each hyperlink from top navigation and it's succesfully loading external .aspx pages (for example,[URL]. The problem is when user comes on the application on first time, it only shows the .aspx page which has a navigation and a Ajax content place holder which is programmed to be filled with contents on click event.
How to load Ajax contents into the Ajax content place holder on page load without a click event?
