HorizontalAlign Enumeration

Updated: August 2008

Specifies the horizontal alignment of items within a container.

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

public enum HorizontalAlign

Member nameDescription
NotSetThe horizontal alignment is not set.
LeftThe contents of a container are left justified.
CenterThe contents of a container are centered.
RightThe contents of a container are right justified.
JustifyThe contents of a container are uniformly spread out and aligned with both the left and right margins.

The HorizontalAlign enumeration represents the horizontal alignment options for items within a container, such as a TableCell.

The following example shows how setting the HorizontalAlign property of a Panel control changes the horizontal alignment for the text of a Label control that is contained by the Panel control.

        Panel1.HorizontalAlign = HorizontalAlign.Left;
      case "Center":
        Panel1.HorizontalAlign = HorizontalAlign.Center;
      case "Justify":
        Panel1.HorizontalAlign = HorizontalAlign.Justify;
