FlowDirection Enumeration

Defines constants that specify the direction in which consecutive user interface (UI) elements are placed in a linear layout container

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public enum FlowDirection

Member nameDescription
BottomUpElements flow from the bottom of the design surface to the top.
LeftToRightElements flow from the left edge of the design surface to the right.
RightToLeftElements flow from the right edge of the design surface to the left.
TopDownElements flow from the top of the design surface to the bottom.

The FlowDirection enumeration describes the flow direction of consecutive UI elements, typically controls, on a design surface or container such as a form. This enumeration is used by linear layout containers such as FlowLayoutPanel, which stores this information internally in the FlowLayoutPanel.FlowDirection property.

The FlowDirection determines where a new control is placed by default when it is added to a supporting container. The flow direction of the container, along with the Anchor and Dock properties of each contained control, determine the rearrangement of controls when their container is resized.

The FlowLayoutPanel control provides a FlowBreak property to its child controls. Setting the value of the FlowBreak property to true causes the FlowLayoutPanel control to stop laying out controls in the current flow direction and wrap to the next row or column.

The following example shows how to set the FlowDirection property on a FlowLayoutPanel control. This code example is part of a larger example provided for the FlowLayoutPanel control.

    private void flowTopDownBtn_CheckedChanged(
		System.Object sender, 
		System.EventArgs e)
    {
        this.FlowLayoutPanel1.FlowDirection = FlowDirection.TopDown;
    }

    private void flowBottomUpBtn_CheckedChanged(
		System.Object sender, 
		System.EventArgs e)
    {
        this.FlowLayoutPanel1.FlowDirection = FlowDirection.BottomUp;
    }

    private void flowLeftToRight_CheckedChanged(
		System.Object sender, 
		System.EventArgs e)
    {
        this.FlowLayoutPanel1.FlowDirection = FlowDirection.LeftToRight;
    }

    private void flowRightToLeftBtn_CheckedChanged(
		System.Object sender, 
		System.EventArgs e)
    {
        this.FlowLayoutPanel1.FlowDirection = FlowDirection.RightToLeft;
    }
