ContentDirection Enum

Definition

Represents the direction in which to display controls that include text in a container control.

public enum class ContentDirection
public enum ContentDirection
type ContentDirection = 
Public Enum ContentDirection
Inheritance
ContentDirection

Fields

Name Value Description
NotSet 0

Not set.

LeftToRight 1

Left to right.

RightToLeft 2

Right to left.

Examples

The following example demonstrates how to use the ContentDirection enumeration to set the Panel.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 that the user selects from the list box. Because this example uses English text, 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 Panel.Direction property to the RightToLeft value, if you were displaying text for a language that uses left-to-right order.

Remarks

The ContentDirection enumeration represents the direction in which to display controls that include text in a container control. Controls such as the Panel and WebPart controls have properties that use the ContentDirection enumeration values to specify the direction in which to display child controls that include text.

If you specify the LeftToRight value, child controls that include text display text from left to right and justify the text on the left side of the container control. If you specify the RightToLeft value, child controls that include text display text from right to left and justify the text on the right side of the container control. Use the RightToLeft value to display text for languages that are written from right to left, such as Arabic and Hebrew.
