Control::Show Method ()

.NET Framework (current version)
 

Displays the control to the user.

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

C#
C++
F#
VB
Copy 
public:
void Show()

Showing the control is equivalent to setting the Visible property to true. After the Show method is called, the Visible property returns a value of true until the Hide method is called.

The following code example displays an about dialog box and temporarily draws a blue square on its surface. This example requires that you have defined a class that derives from Form named AboutDialog.

C#
C++
VB
Copy 
private:
   void menuItemHelpAbout_Click( Object^ /*sender*/, EventArgs^ /*e*/ )
   {
      // Create and display a modeless about dialog box.
      AboutDialog^ about = gcnew AboutDialog;
      about->Show();

      // Draw a blue square on the form.
      /* NOTE: This is not a persistent object, it will no longer be
                  * visible after the next call to OnPaint. To make it persistent,
                  * override the OnPaint method and draw the square there */
      Graphics^ g = about->CreateGraphics();
      g->FillRectangle( Brushes::Blue, 10, 10, 50, 50 );
   }
