View 4 RepliesI am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.
---------------------------------------------------------------------------------------------------
<sys.web>......<customErrors mode="On" defaultRedirect="~/Error.aspx"></customErrors>...</sys.web>
---------------------------------------------------------------------------------------------------
And even i tried in Global.asax page in Application_Error() method like below
Exception ex = Server.GetLastError();Response.Redirect("~/Error.aspx?errmsg="+ex.message);Server.ClearError();
And in my Error.aspx.cs page i have placed a label and i have written code like this
protected void Page_Load(object sender, EventArgs e) {
Label1.Text=Request["errmsg"];
}
But it is not getting redirected my error page and not displaying anything on it.
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...
[Code]....
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.

View 1 RepliesI have an ASP.Net site using Forms authentication. One of the aspx pages loads a WinForms user control hosted in IE. That control must connect with a WCF service located in the same ASP.Net web site.How can I make the WCF service secure? Currently I have set the WCF service to use AspNetCompatibilityRequirements mode but the user control hosted in IE can't connect to the WCF service as it isn't logged in.

when a user enters a bad email I am doing a check on this and throwing an exception message as follows, this works fine on the test site but for some reason the same code on the live site gives a "internal server error" (http code 500). The code below:

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.

View 2 RepliesI am trying to implement the Ajax HtmlEditor into my application. I currently am using a regular TextBox to load and save some data to some EMail template files and had to do some work-arounds to get it to accept the HTML Input. I am trying to upgrade it to use the Editor, but as soon as I insert the Editor and do a PostBack, I receive the Security Exception below. There is absolutely no change to the code-behind, so I don't understand the issue. There is so little on Google for the Version 3.5 Editor that I'm stumped. I have Debugging enabled, but it won't give me the Soruce Error either.
