-/**
- * TButton class
- *
- * 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.
- *
- * 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 TButton
- * components on a Web page and programmatically determine which one is clicked
- * with what parameter. You can provide an event handler for
- * {@link onCommand OnCommand} 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}.
- *
- * 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 OnClick} 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.
- *
- * TButton displays the {@link setText Text} property as the button caption.

+ * TCheckBox class

+ *

+ * TCheckBox displays a check box on the page.

+ * You can specify the caption to display beside the check box by setting

+ * the {@link setText Text} property.  The caption can appear either on the right

+ * or left of the check box, which is determined by the {@link setTextAlign TextAlign}

+ * property.

+ *

+ * To determine whether the TCheckBox component is checked, test the {@link getChecked Checked}

+ * property. The {@link onCheckedChanged OnCheckedChanged} event is raised when

+ * the {@link getChecked Checked} state of the TCheckBox component changes

+ * between posts to the server. You can provide an event handler for

+ * the {@link onCheckedChanged OnCheckedChanged} event to  to programmatically

+ * control the actions performed when the state of the TCheckBox component changes

+ * between posts to the server.

+ *

+ * If {@link setAutoPostBack AutoPostBack} is set true, changing the check box state

+ * will cause postback action. And if {@link setCausesValidation CausesValidation}

+ * is true, validation will also be processed, which can be further restricted within

+ * a {@link setValidationGroup ValidationGroup}.

+ *

+ * Note, {@link setText Text} is rendered as is. Make sure it does not contain unwanted characters

+ * that may bring security vulnerabilities.

-/**
- * TImageButton class
- *
- * 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.
- *
- * 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 OnCommand} 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}.
- *
- * 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 OnClick} 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 OnClick}
- * 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.
- *
- * TImageButton displays the {@link setText Text} property as the hint text to the displayed image.

+/**

+ * TImageButton class

+ *

+ * 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.

+ *

+ * 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 OnCommand} 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}.

+ *

+ * 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 OnClick} 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 OnClick}

+ * 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.

+ *

+ * TImageButton displays the {@link setText Text} property as the hint text to the displayed image.

+ *

-/**
- * TLinkButton class
- *
- * TLinkButton creates a hyperlink style button on the page.
- * TLinkButton has the same appearance as a hyperlink. However, it is mainly
- * used to submit data to a page. Like {@link TButton}, you can create either
- * a <b>submit</b> button or a <b>command</b> button.
- *
- * 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 OnCommand} 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}.
- *
- * 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 TLinkButton component is a submit button.
- * You can provide an event handler for the {@link onClick OnClick} 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.
- *
- * TLinkButton will display the {@link setText Text} property value
- * as the hyperlink text. If {@link setText Text} is empty, the body content
- * of TLinkButton will be displayed. Therefore, you can use TLinkButton
- * as an image button by enclosing an &lt;img&gt; tag as the body of TLinkButton.

+/**

+ * TLinkButton class

+ *

+ * TLinkButton creates a hyperlink style button on the page.

+ * TLinkButton has the same appearance as a hyperlink. However, it is mainly

+ * used to submit data to a page. Like {@link TButton}, you can create either

+ * a <b>submit</b> button or a <b>command</b> button.

+ *

+ * 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 OnCommand} 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}.

+ *

+ * 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 TLinkButton component is a submit button.

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

+ *

+ * TLinkButton will display the {@link setText Text} property value

+ * as the hyperlink text. If {@link setText Text} is empty, the body content

+ * of TLinkButton will be displayed. Therefore, you can use TLinkButton

+ * as an image button by enclosing an &lt;img&gt; tag as the body of TLinkButton.

+ *
