Answer 1

Assuming your view.aspx page has a TextBox control for the class name called txtClassName, you can add a query string to your edit.aspx like this:

<asp:LinkButton ID="EditLink" runat="server" Text="Edit" PostBackUrl='<%# "edit.aspx?classname=" + txtClassName.Text %>' />

This creates the url in this format:

edit.aspx?classname=class1

Then, in the Page_Load event of your edit.aspx page, you can retrieve the selected class name like this:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        string className = Request.QueryString["classname"];

        // code to output the class details      
        // for example, if you want to add the class name to a dropdownlist:
        DropDown1.Items.Add(className);
    }
}
