Examples

The following example creates and initializes a VScrollBar and adds it to a Form.

private:
   void InitializeMyScrollBar()
   {
      // Create and initialize a VScrollBar.
      VScrollBar^ vScrollBar1 = gcnew VScrollBar;
      
      // Dock the scroll bar to the right side of the form.
      vScrollBar1->Dock = DockStyle::Right;
      
      // Add the scroll bar to the form.
      Controls->Add( vScrollBar1 );
   }
private void InitializeMyScrollBar()
 {
    // Create and initialize a VScrollBar.
    VScrollBar vScrollBar1 = new VScrollBar();
    
    // Dock the scroll bar to the right side of the form.
    vScrollBar1.Dock = DockStyle.Right;
    
    // Add the scroll bar to the form.
    Controls.Add(vScrollBar1);
 }
 
Private Sub InitializeMyScrollBar()
    ' Create and initialize a VScrollBar.
    Dim vScrollBar1 As New VScrollBar()
    
    ' Dock the scroll bar to the right side of the form.
    vScrollBar1.Dock = DockStyle.Right
    
    ' Add the scroll bar to the form.
    Controls.Add(vScrollBar1)
End Sub

Remarks

Most controls that need scroll bars already provide them and do not require this control. This is true of a multiline TextBox control, a ListBox, and a ComboBox, for example.

You can use this control to implement scrolling in containers that do not provide their own scroll bars such as a PictureBox or for user input of numeric data. The numeric data can be displayed in a control or used in code. The Minimum and Maximum properties determine the range of values the user can select. The LargeChange property determines the effect of clicking within the scroll bar but outside the scroll box. The SmallChange property determines the effect of clicking the scroll arrows at each end of the control.
