Adding Button Controls to a Web Forms Page
Controls You Can Use on Web Forms ASP.NET Standard Controls Button Controls
Adding buttons to a page is a simple process.
To add a Button Web server control to a Web Forms page
- Declare an <asp:Button> or <asp:LinkButton> element on the page.
- Set the caption by setting the control's Text property.
- Assign the handler that will receive control when the onClick event of the button occurs ( i.e., when a user clicks the control ).
<asp:button text="Click Me" onClick="doSomething" runat="server" />

Because buttons execute commands, it can be useful to specify an access key for a button. Users can then press ALT plus the access key to choose the button. Note, though, that access keys are not supported in all browsers.
To define a button access key
- Set the accessKey property to a single character. For example, to make the access key ALT plus the character "B", specify "B" as the value of the accessKey property.
<asp:button text="Click Me" accessKey="c" onClick="doSomething" runat="server" />
NOTE: In Windows applications, access keys are typically indicated on a button using an underlined character. This facility is not available for Button Controls due to restrictions in HTML. If you want to be able to display the access key for a button, you can use the HtmlInputButton or HtmlButton control.
Adding an ImageButton control is slightly more involved that working with other button types. See Creating Graphical Button Controls.
