LinkButton control is used to create a hyperlink-style button on a Web Forms page. Specify the text to display in the LinkButton control by either setting the Text property or placing the text between the opening and closing tags of the LinkButton control. You can create either a submit button or a command button.
A submit button does not have a command name associated with the button and simply posts the Web page back to the server. By default, a LinkButton control is a submit button. You can provide an event handler for the Click event to programmatically control the actions performed when the submit button is clicked.
By setting the CommandName property, you can associate a command name with the command button, such as Sort. This allows you to create multiple LinkButton controls on a Web page and programmatically determine which LinkButton control is clicked. You can also use the CommandArgument property with a command button to provide addition information about the command to perform, such as Ascending. You can provide an event handler for the Command event to programmatically control the actions performed when the command button is clicked.
