Control.SetStyle Method (ControlStyles, Boolean)


Sets a specified ControlStyles flag to either true or false.

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

protected void SetStyle(
	ControlStyles flag,
	bool value


Type: System.Windows.Forms.ControlStyles

The ControlStyles bit to set.

Type: System.Boolean

true to apply the specified style to the control; otherwise, false.

Control style bit flags are used to categorize supported behavior. A control can enable a style by calling the SetStyle method and passing in the appropriate ControlStyles bit (or bits) and the Boolean value to set the bit(s) to. To determine the value assigned to a specified ControlStyles bit, use the GetStyle method and pass in the ControlStyles member to evaluate.


Setting the control style bits can substantially change the behavior of the control. Review the ControlStyles enumeration documentation to understand the effects of changing the control style bits before calling the SetStyle method.

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(ControlStyles.DoubleBuffer | 
      ControlStyles.UserPaint |
