WebControl.Width Property

Gets or sets the width of the Web server control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public virtual Unit Width { get; set; }
/** @property */
public Unit get_Width ()

/** @property */
public void set_Width (Unit value)

public function get Width () : Unit

public function set Width (value : Unit)

Not applicable.

Property Value

A Unit that represents the width of the control. The default is Empty.

Exception typeCondition

ArgumentException

The width of the Web server control was set to a negative value.

Use the Width property to specify the width of the Web server control.

NoteNote:

This property does not render for all controls in browsers earlier than Microsoft Internet Explorer version 4. Controls that do not render this property in earlier browsers include Label, HyperLink, LinkButton, and any validation controls. The CheckBoxList, RadioButtonList and DataList also do not render this property in earlier browsers when their RepeatLayout property is set to RepeatLayout.Flow. Furthermore, only unit types of Pixel and Percentage are supported in earlier browsers.

Because this property is nonstandard HTML, Web server controls that display as a table, such as Table and DataGrid, do not support this property in browsers earlier than Microsoft Internet Explorer version 4.

NoteNote:

To set the Width property declaratively to a unit type other than the default of Pixel, you must create a new unit type specific to the unit type you want. For example, to set a control's Width property to a percentage value of 100, you could do the following:

myWebControl.width = Unit.Percentage(100);

For more information on the unit types available for the Width property, see the Unit class.

The following example illustrates how to declaratively set the Width property of the Table control, inherited from the WebControl base class.
