Panel.Direction Property

Definition

Gets or sets the direction in which to display controls that include text in a Panel control.

public:
 virtual property System::Web::UI::WebControls::ContentDirection Direction { System::Web::UI::WebControls::ContentDirection get(); void set(System::Web::UI::WebControls::ContentDirection value); };
public virtual System.Web.UI.WebControls.ContentDirection Direction { get; set; }
member this.Direction : System.Web.UI.WebControls.ContentDirection with get, set
Public Overridable Property Direction As ContentDirection

Property Value

One of the ContentDirection enumeration values. The default is NotSet.

Examples

The following code example demonstrates how to programmatically set the Direction property. A ListBox control is populated with the ContentDirection enumeration values. The display direction of the label and radio buttons in the panel change, based on the value the user selects from the list box. Note that this example uses English text. Therefore, when the RightToLeft value is selected, the text is justified on the right side of the Panel control, but the left-to-right order of the English text is maintained. In a real-world application you would not set the Direction property to RightToLeft if you were displaying text for a left-to-right language.

Note

The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information on the Web Forms code model, see ASP.NET Web Forms Page Code Model.

Value Description
NotSet The content direction is not set.
LeftToRight The content direction is left to right.
RightToLeft The content direction is right to left.

If you specify LeftToRight, child controls that include text display from left to right. If you specify RightToLeft, child controls that include text display right to left. Use RightToLeft to display text for languages that are written from right to left, such as Arabic or Hebrew.
