Once you re finished, your ASPNET code should appear as the following:
Mixedaspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Mixedaspxcs" Inherits="Mixed" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 10 Transitional//EN" "http://wwww3org/TR/xhtml1/DTD/xhtml1-transitionaldtd"> <html xmlns="http://wwww3org/1999/xhtml"> <head runat="server"> <title>Mixed Controls</title> </head> <body> <form id="form1" runat="server"> <div> <input id="Text1" type="text" runat="server"/><br > <textarea id="TextArea1" cols="20" rows="2" runat="server" /><br /> <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" /> <br /> <img alt="bird" longdesc="big bird" src="toucanjpg" style="width: 308px; height: 231px" /> </div> </form> </body> </html>
An equally important part of this exercise is to see if the different mixed types of HTML forms and the Standard ASPNET button will work together Also, remember that

the objects include a JPEG file, and the image file must play nicely in the sandbox with the other elements that are set up using runat="server" in their tag containers Note, however, that nowhere in the Mixed partial class is there any reference to the <img> tag
C# Mixedaspxcs
using System; public partial class Mixed : SystemWebUIPage { protected void Button1_Click(object sender, EventArgs e) { TextArea1Value = Text1Value; } }
Once you ve entered the code, go ahead and test it As you can see in Figure 5-4, the two different HTML forms appear along with the Standard ASPNET button and the image of the bird

Using HTML Forms Interactively
You can use the HTML forms for data input in an ASPNET application, but to use HTML buttons, we re going to have to put in some special code rather than relying on good old Visual Studio 2008 to do all the work First of all, you will need to use a submit button when you re setting up your button to fire a C# event handler Second, you ll need a special format to specify an event The following shows the key elements you will need to enter by hand after you have dragged the Input (Submit) button from the Toolbox to the stage:
<input id="MyButton" type="submit" value="Button" OnServerClick= "My_Click" runat="server" />
Two key attributes must be included First, you need the attribute
OnServerClick="My_Click"
The value does not need to be "My_Click" any name will do The value ("My_Click") is the event name you will use with the C# portion of the application The second key attribute tells the script that this button is a server-side application It is required for all HTML tags that are to be used with C#
runat="server"
In the debugging process the first thing to check is whether the runat="server" has been added to your HTML tag In the C# code the easiest approach is to change the default C# event handler code from
protected void Page_Load(object sender, EventArgs e) { //Operational code }
protected void My_Click(object sender, EventArgs e) { //Operational code }

Ask the Expert
Q: A:
Can you use any event handler name you want What if I wanted to use Page_ Load as an event handler name for a button I know it doesn t make much sense, but I m just curious
Because Page_Load is a page event, it will not respond to a button-click event In fact, ASPNET 35 and C# 30 have several page events such as Page_Unload, Page_Init, and Page_LoadComplete that will not respond to the button click However, if you use an event handler name like Page_Click with a button, it responds just as well as any other name associated with a Button control Until you learn more, though, I d suggest that you not preface your event name with Page_ unless it is one that you want to have respond to a page event
As you can see, the change is minimal You re just substituting your own handler name for the default Page_Load All C# will be looking for is the right event name based on the attribute OnServerClick="My_Click" in your button tag and runat="server"
