Form.AutoScroll Property

Gets or sets a value indicating whether the form enables autoscrolling.

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

Public Overrides Property AutoScroll As Boolean

Property Value

Type: System.Boolean
true to enable autoscrolling on the form; otherwise, false. The default is false.

If this property is set to true, scroll bars are displayed on the form if any controls are located outside the form's client region. Additionally, when autoscrolling is on, the client area of the form automatically scrolls to make the control with input focus visible.

You can use this property to prevent users from losing the ability to view controls when their video resolution settings are set to a low resolution.

The following code example demonstrates how to use the AutoScroll property to enable the display of controls that are outsize the client area of a form. The example creates a new form and adds a Button control to the form. The Button control is positioned outsize the client area of the new form. The AutoScroll property is set to true to display scroll bars on the form to enable the user to scroll to the control. This example requires that the method defined in this example is called from another form in an event handler or other method.

Private Sub DisplayMyScrollableForm()
   ' Create a new form. 
   Dim form2 As New Form()
   ' Create a button to add to the new form. 
   Dim button1 As New Button()
   ' Set text for the button.
   button1.Text = "Scrolled Button" 
   ' Set the size of the button.
   button1.Size = New Size(100, 30)
   ' Set the location of the button to be outside the form's client area.
   button1.Location = New Point(form2.Size.Width + 200, form2.Size.Height + 200)

   ' Add the button control to the new form.
   ' Set the AutoScroll property to true to provide scrollbars.
   form2.AutoScroll = True 

   ' Display the new form as a dialog box.
End Sub
