I have an existing project with a silverlight3 app. First I created SALESservice.svc.This is working fine. Now I added another TARGETservice.svc to my project and rebuilded my entire project but when I am trying to add the service reference in to the silverlight app I get the following error:
There was an error downloading metadata from the address.verify that you have entered a valid address. I didn't write any code in ISALESservice.svc AND ITARGETservice.svc . I have written in SALESservice.svc.cs AND TARGETservice.svc.cs files.Is this causing error? But for SALESservice.svc it is working. I didn't add any code in web.config file.

After many years reading this forum... I didn't found the solution to my actual problem... When I tought... this could be a big problem... I have a web app wich doesn't have try catch blocks in every method... so I need to implement a generic solution to handle exceptions and the most important... show some BO exceptions to user inside a MessageUserControl (ASCX) wich uses AJAX. this is the big problem, I tried many solutions, application_error, a specific log module, page_error... and with all I got to the same problem...
The UpdatePanel, when it got an unhandled exception, it fires the events (application_error, page_error) or even the httpmodule, but I think it call an Response.End, wich stops any action in the page... and this is just I don't want to do... I need to display the message to the client. this is the call to show the message...
My page wich gots an unhandled exception are inside an UpdatePanel, if I remove it, the message shows UP! I'm working on this for 5 long days.
I have a web form with about 20 fields all validated, rather than use the validation summary control.
I would like a one line alert at the foot of the form that says something along the lines of "errors were found check the fields highlighted with a *" rather than an explanation for each field that has failed validation.
Seem simple enough in theory but i cant work it out.
Is there a line of VB.net code i could use to determine if validation has failed on one or more of my validators and maybe show a label with the "errors were found please check the fields highlighted with a *" message?
how to solve the AJAX POST problem on ASP NET MVC running on IIS7, basically when you use an Android 2.1 phone and load an ASP NET MVC website on IIS7, and you click on a input button that subsquently makes an AJAX call, you get on a high level, the error window shopwing Error: NETWORK_ERR: XMLHttpRequest Exception 101. I have generated a TempData variable containing some data, and when a RedirectToAction call is made to the controller, the TempData is null. am wondering if anyone has managed to solve this problem at all, and I have searched everywhere but no one seems to know the solution for it.

I am actually bit confused to say. I googled for applying styles in my spreadsheet i got some functions in which they mention about the font, borders etc which i need but i dont know where should i use or how should i implement. When i tried to implement like cell.StyleIndex=8 // Which is modified as per my need but there is no effect in the cells
My application sets the css styesheet via code. The <link> statement below (line #8) is how it is set. The code that sets is is shown at line #23.On my main form, I had to add the runat=server tag on the <head> in order to get my Ajax Editor control to work. When I add runat=server, the stylesheet no longer gets set. When I look at the source, the "<%" is changed to "<%" (line #8 below). I assume this is why my stylesheet is not being set. When I hard code the stylesheet (line #9), it works fine. How do I repair this?
