Introduction

The control is a container for other controls. It is especially useful when you want to generate controls programmatically, hide/show a group of controls, or localize a group of controls. The property is useful for localizing a control's content to display text for languages that are written from right to left, such as Arabic or Hebrew. The control provides several properties that allow you to customize the behavior and display of its contents. Use the property to display a custom image for the control. Use the property to specify scroll bars for the control.

Represents a control that acts as a container for other controls.

Constructor To be added

Initializes a new instance of the class.

1.0.5000.0 2.0.0.0 Method System.Void a The method is used primarily by control developers.

Adds information about the background image, alignment, wrap, and direction to the list of attributes to render.

1.0.5000.0 2.0.0.0 Property System.String To be added: an object of type 'string' Use this property to display a custom image for the control. If the image is smaller than the , it will be tiled to fill in the . This property is supported only on browsers that support HTML 4.0 or later.

Creates a style object that is used internally by the control to implement all style related properties.

A that contains the style properties of the control. Property 2.0.0.0 System.Web.UI.Themeable(false) System.String To be added. Use the property to indicate which button gets clicked when the control has focus and the user presses the ENTER key. The can be set to the identifier for a control or any control that implements the interface except a control. If the is set to a control that does not implement the interface, or to a control that is not contained in the control, the control throws an exception while rendering. Setting the property is not supported for the following scenarios: Setting focus outside of the input controls in the panel and then pressing the ENTER key. The default post back action is not guaranteed to trigger. Pressing the ENTER key with focus inside a multi-line textbox. In a multi-line textbox, pressing the ENTER key should create a new line in the textbox which is the expected behavior. In browsers where the pressing the ENTER key inside a multi-line textbox triggers a post back but you want the ENTER key to create a new line instead you can attach a JavaScript function to the input control. The script should capture the ENTER key and stop the post back. For example, you can use the property collection to add client script for the onKeyPress event. Referencing a default button that is a control. Only and controls are supported. Changing the programmatically during an asynchronous post back when the control is not inside of an control. Asynchronous post backs can be enabled on a page by adding one or more controls to the page. controls can be used to update selected regions of a page instead of updating the whole page with a postback. For more information, see UpdatePanel Control Overview and Partial-Page Rendering Overview. Setting this property by themes or style sheet themes. For more information, see and ASP.NET Themes Overview.

Gets or sets the identifier for the default button that is contained in the control.

Property 2.0.0.0 System.Web.UI.WebControls.ContentDirection To be added. Use the property to specify the display direction for controls that include text in a control.
