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

Type: System.Booleantrue if the control and all its child controls are displayed; otherwise, false. The default is true.
The following code example uses the derived classes VScrollBar and HScrollBar and sets their Visible property values, based on the size of an Image being displayed in a PictureBox control. This example requires that a PictureBox has been created on a form and that HScrollBar and VScrollBar controls have been created on the PictureBox. This code should be called when the image is loaded into the picture box and by the Resize event of the form.
Public Sub DisplayScrollBars() ' Display or hide the scroll bars based upon ' whether the image is larger than the PictureBox. If pictureBox1.Width > pictureBox1.Image.Width Then hScrollBar1.Visible = False Else hScrollBar1.Visible = True End If If pictureBox1.Height > pictureBox1.Image.Height Then vScrollBar1.Visible = False Else vScrollBar1.Visible = True End If End Sub 'DisplayScrollBars
