Manipulating HTML Server Controls

   <%@ Page Language="VB" %>

   <script runat="server">
   Sub Click(Sender as Object, e as EventArgs)
   select case Sender.Value
   case "Left"
   word_image.align = "left"
   case "Right"
   word_image.align = "right"
   case "Center"
   word_image.align = "center"
   end select

   Left.Style("Border-Style") = "notset"
   Right.Style("Border-Style") = "notset"
   Center.Style("Border-Style") = "notset"

   Sender.Style("Border-Style") = "inset"
   end Sub
   </script>

   <html><body>
   <font size="5">Sam's Teach Yourself ASP.NET in
   21 Days: Day 5 </font><hr><p>

   <form runat="server">
   <input type="Button" id="Left" runat="server"
   Value="Left" OnServerClick="Click" />
   <input type="Button" id="Center" runat="server"
   Value="Center" OnServerClick="Click" />
   <input type="Button" id="Right" runat="server"
   Value="Right" OnServerClick="Click" />
   </form>

   <img src="word.gif" id="word_image" runat="server">
   <div id="Label1" runat="server">This is an example
   of text. When the buttons above are clicked, the image
   will move around the text accordingly.<p> This example
   demonstrates the HtmlImage and HtmlInputButton controls.
   </div>

   </body></html>

Saving Values in the State Bag

   <%@ Page Language="VB" %>

   <script runat="server">
   Sub Page_Load(Sender as Object, e as EventArgs)
   if not Page.IsPostBack then
   ViewState("StartTime") = DateTime.Now
   lblMessage.Text = "The time is now: " & _
   ViewState("StartTime")
   end if
   end sub

   Sub Submit(obj as object, e as EventArgs)
   lblMessage.Text = "The time is now: " & _
   DateTime.Now & "<br>started at: " & _
   ViewState("StartTime")
   end Sub
   </script>

   <html><body>
   <font size="5">Sam's Teach Yourself ASP.NET in 21
   Days: Day 5 </font><hr><p>

   <form runat="server">
   <asp:Button id="btSubmit" runat="server" Text="Submit"
   onClick="Submit" />
   <p>
   <asp:Label id="lblMessage" runat=server />
   </form>
   </body></html>

Checking the IsPostBack Property

   <%@ Page Language="C#" %>

   <script runat="server">
   void Page_Load(Object Sender, EventArgs e) {
   if (!Page.IsPostBack) {
   lblMessage.Text = "Hello world!!!!";
   }
   }

   void Submit(Object Sender, EventArgs e) {
   lblMessage2.Text = "Form posted";
   }
   </script>

   <html><body>
   <form runat="server">
   <asp:Button id="btSubmit" runat="server" Text="Submit"
   onClick="Submit" />
   <p>
   <asp:Label id="lblMessage" runat=server />
   <p>
   <asp:Label id="lblMessage2" runat=server />
   </form>
   </body></html>

Event Handler

1: <%@ Page Language="VB" %>
2:
3: <script runat="server">
4: Sub Button1_Click(Sender as Object, e as EventArgs)
5: Label1.Text="You clicked <b>" & Sender.Text & "</b>"
6: end Sub
