Control.UpdateStyles Method

Forces the assigned styles to be reapplied to the control.

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

protected:
void UpdateStyles ()
protected void UpdateStyles ()
protected function UpdateStyles ()
Not applicable.

This method calls the CreateParams method to get the styles to apply. The styles assigned to the Style and ExStyle properties of the CreateParams assigned to the control's CreateParams property are reapplied. The control is repainted to reflect the style changes if necessary.

The UpdateStyles method has no effect if the IsHandleCreated property value is false.

The following code example enables double-buffering on a Form and updates the styles to reflect the changes.

public:
   void EnableDoubleBuffering()
   {
      // Set the value of the double-buffering style bits to true.
      this->SetStyle( static_cast<ControlStyles>(ControlStyles::DoubleBuffer | ControlStyles::UserPaint | ControlStyles::AllPaintingInWmPaint), true );
      this->UpdateStyles();
   }

public void EnableDoubleBuffering()
{
    // Set the value of the double-buffering style bits to true.
    this.SetStyle(ControlStyles.DoubleBuffer | ControlStyles.UserPaint | 
        ControlStyles.AllPaintingInWmPaint, true);
    this.UpdateStyles();
} //EnableDoubleBuffering
