Action Controls in ASP.NET

Introduction and Demonstration

Action controls allow users to perform some action on that page, such as navigating to a different URL, submitting a form, resetting a form's values, or executing a client script. Here is list of such controls.
Control Purpose **************************************************** Button Displays a command button that posts a form to the server when clicked. ImageButton Displays an image that posts a form to the server when clicked. LinkButton Displays a hyperlink text that posts a form to the server when clicked. Hyperlink Displays a hyperlink text that navigates from one page to another when clicked.

The simplified syntax of these controls is as follows:

<asp:button id="MyButton" text="Click Me!!" runat="server"/>

<asp:imagebutton id="MyImageButton"

imageurl="aspnetian.jpg" runat="Server"/>

<asp:linkbutton id="MyLinkButton" text="Click Me" runat="server"/>

<asp:hyperlink id="MyHyperLink"

text="Click Me"

navigateurl="ActionControls.aspx"

target="_blank"

runat="server"/>

The controls can then be accessed programmatically with code fragments like the following:

MyButton.CommandName = "Sort"

MyImageButton.CommandArgument = "Ascending"

MyLinkButton.CommandName = "Filter"

MyHyperLink.NavigateUrl = "http://web.itorian.com/"

Index.aspx Page:

<%@ Page Language="vb" %>

<html>

<head>

<title>Action Control Example</title>

Sub Page_Load( )

MyButton.CommandName = "Sort"

MyImageButton.CommandArgument = "Ascending"

MyLinkButton.CommandName = "Filter"

MyHyperLink.NavigateUrl = " http://dotnet.oreilly.com/"

End Sub
