<pre lang="PHP"></pre>Hello
I want to know is there anything similar to class in vb.net which can be call on all the forms just by refering its name.
similarly how can i make it in asp.net. since, asp.net some controls in a class file it shows error i.e. object reference not set to an instance of an object.
Thanks.

i don't really get the question but...

you can simply create a class make it public and add public method in that class and access that method from your aspx.cs code behind.

Hello Mirzamujib,

pardon me for the nasty code as i am doing it real quick so here's the code to call class member from aspx page.

this is WebForm1.aspx

HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<head  runat="server">
    <title></title>
</head>
<body>
    <form id="form1"  runat="server">
    <div>
        <%=new WebApplication1.Class1().MyName %>
    </div>
    </form>
</body>
</html>

this is another class

C#

namespace WebApplication1
{
    public class Class1
    {
        public string MyName { get { return "naruto"; } }
    }
}

hopefully you get the idea... sorry for the code
