public:
[BrowsableAttribute(true)]

    void set(bool value);
}

[<BrowsableAttribute(true)>]

<BrowsableAttribute(True)>
Public Property Visible As Boolean

Property Value

Type: System.Boolean

true if the control is displayed; otherwise, false. The default is true.

Remarks

The Visible property can be used to make graphics objects created by using a LineShape, OvalShape, or RectangleShape control appear and disappear at run time.

Examples

The following example demonstrates how to use the Visible property to switch between two different shapes at run time. This example requires that you have a RectangleShape control named RectangleShape1 and an OvalShape control named OvalShape1 on a form. For best results, make both controls the same size and position one on top of the other.

private void ShapeVisible_Load(System.Object sender, System.EventArgs e)
{
    // Hide the oval.
    ovalShape1.Visible = false;
}

private void Shapes_Click(System.Object sender, System.EventArgs e)
{
    if (ovalShape1.Visible == true)
    // Hide the oval.
    {
        ovalShape1.Visible = false;
        // Show the rectangle.
        rectangleShape1.Visible = true;
    }
    else
    {
        // Hide the rectangle.
        rectangleShape1.Visible = false;
        // Show the oval.
        ovalShape1.Visible = true;
    }
}

Private Sub ShapeVisible_Load() Handles MyBase.Load
    ' Hide the oval.
    OvalShape1.Visible = False
End Sub

Private Sub Shapes_Click() Handles RectangleShape1.Click,
                                   OvalShape1.Click

    If OvalShape1.Visible = True Then
        ' Hide the oval.
        OvalShape1.Visible = False
        ' Show the rectangle.
        RectangleShape1.Visible = True
    Else
        ' Hide the rectangle.
        RectangleShape1.Visible = False
        ' Show the oval.
        OvalShape1.Visible = True
    End If
End Sub
