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.

ControlPurpose
ButtonDisplays a command button that posts a form to the server when clicked.
ImageButtonDisplays an image that posts a form to the server when clicked.
LinkButtonDisplays a hyperlink text that posts a form to the server when clicked.
HyperlinkDisplays 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://www.itorian.com"
