 /**

  * TButton class

  *

- * TButton creates a click button on the page.

+ * TButton creates a click button on the page. It is used to submit data to a page.

+ * You can create either a <b>submit</b> button or a <b>command</b> button.

  *

- * You can create either a <b>submit</b> button or a <b>client</b> button by setting

- * <b>UseSubmitBehavior</b> property. Set <b>Text</b> property to specify the button's caption.

- * Upon clicking on the button, on the server side two events are raised by the button:

- * <b>OnClick</b> and <b>OnCommand</b>. You can attach event handlers to these events

- * to respond to the button click action. For <b>OnCommand</b> event, you can associate

- * it with a command name and parameter by setting <b>CommandName</b> and <b>CommandParameter</b>

- * properties, respectively. They are passed as the event parameter to the <b>OnCommand</b>

- * event handler (see {@link TCommandEventParameter}).

+ * A <b>command</b> button has a command name (specified by

+ * the {@link setCommandName CommandName} property) and and a command parameter

+ * (specified by {@link setCommandParameter CommandParameter} property)

+ * associated with the button. This allows you to create multiple TLinkButton

+ * components on a Web page and programmatically determine which one is clicked

+ * with what parameter. You can provide an event handler for

+ * {@link onCommand Command} event to programmatically control the actions performed

+ * when the command button is clicked. In the event handler, you can determine

+ * the {@link setCommandName CommandName} property value and

+ * the {@link setCommandParameter CommandParameter} property value

+ * through the {@link TCommandParameter::getName Name} and

+ * {@link TCommandParameter::getParameter Parameter} properties of the event

+ * parameter which is of type {@link TCommandEventParameter}.

  *

- * Clicking on button can trigger form validation, if <b>CausesValidation</b> is true.

- * And the validation may be restricted within a certain group of validator controls by

- * setting <b>ValidationGroup</b> property.

+ * A <b>submit</b> button does not have a command name associated with the button

+ * and clicking on it simply posts the Web page back to the server.

+ * By default, a TButton component is a submit button.

+ * You can provide an event handler for the {@link onClick Click} event

+ * to programmatically control the actions performed when the submit button is clicked.

+ *

+ * Clicking on button can trigger form validation, if

+ * {@link setCausesValidation CausesValidation} is true.

+ * And the validation may be restricted within a certain group of validator

+ * controls by setting {@link setValidationGroup ValidationGroup} property.

+ * If validation is successful, the data will be post back to the same page.

+ * You can change the postback target by setting the {@link setPostBackUrl PostBackUrl}

+ * property.

+ *

+ * To set the client-side javascript associated with the user's click action,

+ * use the {@link setOnClientClick OnClientClick} property. The value will be rendered

+ * as the <b>onclick</b> attribute of the button.

+ *

+ * TButton displays the {@link setText Text} property as the button caption.

 /**

  * TImageButton class

  *

- * TImageButton displays an image on the Web page and responds to mouse clicks on the image.

- * It is similar to the {@link TButton} control except that the TImageButton also captures the

- * coordinates where the image is clicked.

+ * TImageButton creates an image button on the page. It is used to submit data to a page.

+ * You can create either a <b>submit</b> button or a <b>command</b> button.

  *

- * Write a <b>OnClick</b> event handler to programmatically determine the coordinates

- * where the image is clicked. The coordinates can be accessed through <b>x</b> and <b>y</b>

- * properties of the event parameter which is of type <b>TImageClickEventParameter</b>.

- * Note the origin (0, 0) is located at the upper left corner of the image.

+ * A <b>command</b> button has a command name (specified by

+ * the {@link setCommandName CommandName} property) and and a command parameter

+ * (specified by {@link setCommandParameter CommandParameter} property)

+ * associated with the button. This allows you to create multiple TLinkButton

+ * components on a Web page and programmatically determine which one is clicked

+ * with what parameter. You can provide an event handler for

+ * {@link onCommand Command} event to programmatically control the actions performed

+ * when the command button is clicked. In the event handler, you can determine

+ * the {@link setCommandName CommandName} property value and

+ * the {@link setCommandParameter CommandParameter} property value

+ * through the {@link TCommandParameter::getName Name} and

+ * {@link TCommandParameter::getParameter Parameter} properties of the event

+ * parameter which is of type {@link TCommandEventParameter}.

  *

- * Write a <b>OnCommand</b> event handler to make the TImageButton component behave

- * like a command button. A command name can be associated with the component by using

- * the <b>CommandName</b> property. The <b>CommandParameter</b> property

- * can also be used to pass additional information about the command,

- * such as specifying ascending order. This allows multiple TImageButton components to be placed

- * on the same Web page. In the event handler, you can also determine

- * the <b>CommandName</b> property value and the <b>CommandParameter</b> property value

- * through <b>name</b> and <b>parameter</b> of the event parameter which is of

- * type <b>TCommandEventParameter</b>.

+ * A <b>submit</b> button does not have a command name associated with the button

+ * and clicking on it simply posts the Web page back to the server.

+ * By default, a TImageButton control is a submit button.

+ * You can provide an event handler for the {@link onClick Click} event

+ * to programmatically control the actions performed when the submit button is clicked.

+ * The coordinates of the clicking point can be obtained from the {@link onClick Click}

+ * event parameter, which is of type {@link TImageClickEventParameter}.

+ *

+ * Clicking on button can trigger form validation, if

+ * {@link setCausesValidation CausesValidation} is true.

+ * And the validation may be restricted within a certain group of validator

+ * controls by setting {@link setValidationGroup ValidationGroup} property.

+ * If validation is successful, the data will be post back to the same page.

+ * You can change the postback target by setting the {@link setPostBackUrl PostBackUrl}

+ * property.

+ *

+ * To set the client-side javascript associated with the user's click action,

+ * use the {@link setOnClientClick OnClientClick} property. The value will be rendered

+ * as the <b>onclick</b> attribute of the button.

+ *
