FlowLayoutPanel Class

Note: This class is new in the .NET Framework version 2.0.

Represents a panel that dynamically lays out its contents horizontally or vertically.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

Syntax

Visual Basic (Declaration)

<ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch)> _
<ComVisibleAttribute(True)> _
Public Class FlowLayoutPanel
    Inherits Panel
    Implements IExtenderProvider

Visual Basic (Usage)

Dim instance As FlowLayoutPanel

[ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch)] 
[ComVisibleAttribute(true)] 
public class FlowLayoutPanel : Panel, IExtenderProvider

C++

[ClassInterfaceAttribute(ClassInterfaceType::AutoDispatch)] 
[ComVisibleAttribute(true)] 
public ref class FlowLayoutPanel : public Panel, IExtenderProvider

/** @attribute ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch) */ 
/** @attribute ComVisibleAttribute(true) */ 
public class FlowLayoutPanel extends Panel implements IExtenderProvider

JScript

ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch) 
ComVisibleAttribute(true) 
public class FlowLayoutPanel extends Panel implements IExtenderProvider

Remarks

The FlowLayoutPanel control arranges its contents in a horizontal or vertical flow direction. Its contents can be wrapped from one row to the next, or from one column to the next. Alternatively, its contents can be clipped instead of wrapped.

You can specify the flow direction by setting the value of the FlowDirection property. The FlowLayoutPanel control correctly reverses its flow direction in right-to-left (RTL) layouts. You can also specify whether the contents of the FlowLayoutPanel control are wrapped or clipped by setting the value of the WrapContents property.

Any Windows Forms control, including other instances of FlowLayoutPanel, can be a child of the FlowLayoutPanel control. With this capability, you can construct sophisticated layouts that adapt to your form's dimensions at run time.

Docking and anchoring behaviors of child controls differ from the behaviors in other container controls. Both docking and anchoring are relative to the largest control in the flow direction. For more information, see How to: Anchor and Dock Child Controls in a FlowLayoutPanel Control.

Example

The following example shows how to set the FlowDirection and WrapContents properties on a FlowLayoutPanel control.
