Examples

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;
    }

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;
}

Private Sub flowTopDownBtn_CheckedChanged( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles flowTopDownBtn.CheckedChanged

    Me.FlowLayoutPanel1.FlowDirection = FlowDirection.TopDown

End Sub

Private Sub flowBottomUpBtn_CheckedChanged( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles flowBottomUpBtn.CheckedChanged

    Me.FlowLayoutPanel1.FlowDirection = FlowDirection.BottomUp

End Sub

Private Sub flowLeftToRight_CheckedChanged( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles flowLeftToRight.CheckedChanged

    Me.FlowLayoutPanel1.FlowDirection = FlowDirection.LeftToRight

End Sub

Private Sub flowRightToLeftBtn_CheckedChanged( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles flowRightToLeftBtn.CheckedChanged

    Me.FlowLayoutPanel1.FlowDirection = FlowDirection.RightToLeft

End Sub

Remarks

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.
