Control.Visible Property

Gets or sets a value indicating whether the control is displayed.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

[LocalizableAttribute(true)] 
public bool Visible { get; set; }
/** @property */
public boolean get_Visible ()

/** @property */
public void set_Visible (boolean value)

public function get Visible () : boolean

public function set Visible (value : boolean)

Property Value

true if the control is 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 void DisplayScrollBars()
 {
    // Display or hide the scroll bars based upon  
    // whether the image is larger than the PictureBox.
    if (pictureBox1.Width > pictureBox1.Image.Width)
    {
       hScrollBar1.Visible = false;
    }
    else
    {
       hScrollBar1.Visible = true;
    }
    
    if (pictureBox1.Height > pictureBox1.Image.Height)
    {
       vScrollBar1.Visible = false;
    }
    else
    {
       vScrollBar1.Visible = true;
    }
 }
 

public void DisplayScrollBars()
{
    // Display or hide the scroll bars based upon  
    // whether the image is larger than the PictureBox.
    if (pictureBox1.get_Width() > pictureBox1.get_Image().get_Width()) {
        hScrollBar1.set_Visible(false);
    }
    else {
        hScrollBar1.set_Visible(true);
    }

    if (pictureBox1.get_Height() > pictureBox1.get_Image().get_Height()) {
        vScrollBar1.set_Visible(false);
    }
    else {
        vScrollBar1.set_Visible(true);
    }
} //DisplayScrollBars

public function DisplayScrollBars()
 {
    // Display or hide the scroll bars based upon  
    // whether the image is larger than the PictureBox.
    if (pictureBox1.Width > pictureBox1.Image.Width)
    {
       hScrollBar1.Visible = false;
    }
    else
    {
       hScrollBar1.Visible = true;
    }
    
    if (pictureBox1.Height > pictureBox1.Image.Height)
    {
       vScrollBar1.Visible = false;
    }
    else
    {
       vScrollBar1.Visible = true;
    }
 }
