Control.Visible Property

.NET Framework 4.5

Gets or sets a value indicating whether the control and all its child controls are displayed.

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

public bool Visible { get; set; }

Property Value

Type: System.Boolean
true if the control and all its child controls are displayed; otherwise, false. The default is true.

Remarks

Note that even if Visible is set to true, the control might not be visible to the user if it is obscured behind other controls.

Examples

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.

C++

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;
    }
 }
