Gets the text for the ToolTip that is being drawn.

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

public:

	String^ get();
}

Property Value

Type: System::String^

The text that is associated with the ToolTip when the Draw event occurs.

Typically you would use the ToolTipText property to determine what the ToolTip text is when you are custom drawing your ToolTip. You can use the Graphics::DrawString method to customize the drawing of the ToolTip text. If you want to have the ToolTip text drawn using the system specified style, use the DrawText method. The text value comes from the value passed to the SetToolTip method of the ToolTip class.

The following code example demonstrates how to custom draw the ToolTip. The example creates a ToolTip and associates it to three Button controls located on the Form. The example sets the OwnerDraw property to true and handles the Draw event. In the Draw event handler, the ToolTip is custom drawn differently depending on what button the ToolTip is being displayed for as indicated by the DrawToolTipEventArgs::AssociatedControl property.

The code excerpt below demonstrates using the DrawBorder method and using the Bounds, ToolTipText, and Graphics properties. See the DrawToolTipEventArgs class overview for the complete code example.

// Draw a custom background and text if the ToolTip is for button2.
else

// Draw a custom background and text if the ToolTip is for button2.
if ( e->AssociatedControl == button2 )
{
   // Draw the custom background.
   e->Graphics->FillRectangle( SystemBrushes::ActiveCaption, e->Bounds );

   // Draw the standard border.
   e->DrawBorder();

   // Draw the custom text.
   // The using block will dispose the StringFormat automatically.
   StringFormat^ sf = gcnew StringFormat;
   try
   {
      sf->Alignment = StringAlignment::Center;
      sf->LineAlignment = StringAlignment::Center;
      sf->HotkeyPrefix = System::Drawing::Text::HotkeyPrefix::None;
      sf->FormatFlags = StringFormatFlags::NoWrap;
      System::Drawing::Font^ f = gcnew System::Drawing::Font( "Tahoma",9 );
      try
      {
         e->Graphics->DrawString( e->ToolTipText, f, SystemBrushes::ActiveCaptionText, e->Bounds, sf );
      }
      finally
      {
         if ( f )
            delete safe_cast<IDisposable^>(f);
      }

   }
   finally
   {
      if ( sf )
         delete safe_cast<IDisposable^>(sf);
   }
}
