Last week I had a problem when I tried to export an image from the AGS 9.2 to a pdf file. I got this error: “Sys.WebForms.PageRequestManagerTimeoutException The server request timed out” from the Ajax Extension framework. Its occurred because the export operation was relatively long (something like 2 minutes) and the Ajax Extension Callback framework had a timeout.

 

How to solve this problem?
To solve this problem we can increase the timeout. You can change the timeout time by adding a new property to the script manager control. This property is called AsyncPostBackTimeOut and it can help us to define the number of seconds before the request will throw a request timeout exception*.

For example if you want that the timeout will take maximum 10 minutes your code should be look like this:

 

<asp:ScriptManager ID=”ScriptManager1″ runat=”server”

AsyncPostBackTimeOut=”600″ >

</asp:ScriptManager>     

* The default value of the AsyncPostBackTimeOut property is 90 seconds.

When you have created virtual directory of your application created in .Net2.0 and application is not running.
Even everything is fine in web.config, still it is giving error in web.config file.

Error :- The current identity (NT AUTHORITY\NETWORK SERVICE) does not have write access to C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files

Solution is
goto command prompt then navigate to directory

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727

Now run this command

aspnet_regiis -ga "NT AUTHORITY\NETWORK SERVICE"

Everything will wok fine.

Hi,

 I found a nice solution for backing to previous page (client side) in asp.net. it is very simple you can write below command in your code behind then the client browser back to previous page client side with javascript back command: 

 response.redirect("javascript:back(1);")

But if the desire page does not have previous page you have to determine if previous page exist or not, like this:

if page.previouspage is nothing then

 response.redirect("~/default.aspx")

else 

  response.redirect("javascript:back(1);")

end if 

 But many times page.previouspage object is null! instead above method you have to use below method :

if request.urlrefferer is nothing then

 response.redirect("~/default.aspx")

else 

  response.redirect("javascript:back(1);")

end if

You can create a function for removing html tags from html string. here it is:

    Protected Function removeHTML(ByVal html As String) As String
        If String.IsNullOrEmpty(html) Then
            Return ""
        Else
            Return System.Text.RegularExpressions.Regex.Replace(html, "<[^>]*>", String.Empty)
        End If
    End Function

Very often we have a relative URL of some page or resource like "~/img/logo.gif" and we need an absolute URL
to insert it in some control or link (something like "http://www.rezashirazi.com/img/logo.gif")

Asp.Net 2.0 has some very useful methods that could help us to resolve the absolute URL we need.

First of them is Page method ResolveUrl() that converts a relative URL into one that is usable on the requesting client.
This means you we can pass to this method an URL that is relative to the current page, something like this:
and it would return to us a valid relative URL , taking into account the current URL of the Page from where you are calling it.

If you use ASP.NET login control in your website, by default login session of your accounts expired after 20 minutes. For increasing session timeout there are some different methods but the simpleset methos is change your website configuration in web.config file. you have to add below data in your web.config file for this reason:

<sessionState mode ="InProc" timeout="540"/>

<httpRuntime executionTimeout="999999"/>

but If you are using Asp.net login control your session timeout problem exists after these changes. for increasing session timeout of asp.net login control change authentication tag in your web.config to below tag:

<authentication mode="Forms"> <forms timeout="540" slidingExpiration="true" loginUrl="~/Login.aspx" />

</authentication>

Your session expiration time is now 9 hours(540 minutes)!

Hi All,

I did have an error like BC30456: 'Title' is not a member of 'ASP....

On my application the error was cause by the Inherits tag. Both of my child forms had the same Inherits "_Default". Then I changed one and it is ok now

Note: You have to change the Inherits tag in the .aspx and in the related .vb files because your inherits tag is repeated in other pages.

 Exemple .aspx :
<% @ Page Language ="VB" MasterPageFile="~/site.master" AutoEventWireup ="false" CodeFile="samplepage.aspx.vb" Inherits="_Default2" title="Sample Page" %>

Exemple .vb :
Partial Class _Default2 Inherits System.Web.UI.Page

 

<script runat="server">
    protected string now = DateTime.Now.ToString();
    public void Page_Load(object sender, EventArgs e)
    {
        System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();

System.Net.NetworkCredential cred = new System.Net.NetworkCredential("yourid@gmail.com", "yourpassword");

mail.To.Add("a@a.com");
mail.Subject = "subject goes here";

mail.From = new System.Net.Mail.MailAddress(yourid@gmail.com);
mail.IsBodyHtml = true;
mail.Body = "This message has been sent programmatically with GMail";

System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("smtp.gmail.com");
smtp.UseDefaultCredentials = false;
smtp.EnableSsl = true;
smtp.Credentials = cred;
smtp.Port = 587;
smtp.Send(mail);
    }
</script>

Follow the steps below to change the default time session timeout in IIS.

3. In the 'Directory' tab click "Create" button, then click "OK".
4. Click on the "Home Directory" tab, then "Configuration".
5. Click on the "Options" tab.
6. Increase the "Session timeout" value and click "OK" twice until you return to the IIS snap-in.
