Control.SetBoundsCore Method (Int32, Int32, Int32, Int32, BoundsSpecified)


Performs the work of setting the specified bounds of this control.

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

protected virtual void SetBoundsCore(
	int x,
	int y,
	int width,
	int height,
	BoundsSpecified specified


Type: System.Int32

The new Left property value of the control.

Type: System.Int32

The new Top property value of the control.

Type: System.Int32

The new Width property value of the control.

Type: System.Int32

The new Height property value of the control.

Type: System.Windows.Forms.BoundsSpecified

A bitwise combination of the BoundsSpecified values.

Typically, the parameters that correspond to the bounds not included in the specified parameter are passed in with their current values. For example, the Height, Width, or the X or Y properties of the Location property can be passed in with a reference to the current instance of the control. However all values passed in are honored and applied to the control.

The boundsSpecified parameter represents the elements of the controls Bounds changed by your application. For example, if you change the Size of the control, the boundsSpecified parameter value is the Size value of BoundsSpecified. However, if the Size is adjusted in response to the Dock property being set, the boundsSpecified parameter value is the None value of BoundsSpecified.


On Windows Server 2003 systems, the size of a Form is restricted by the maximum pixel width and height of the monitor.

Notes to Inheritors:

When overriding SetBoundsCore in a derived class, be sure to call the base class's SetBoundsCore method to force the bounds of the control to change. Derived classes can add size restrictions to the SetBoundsCore method.

The following code example overrides the SetBoundsCore method to ensure that the control remains a fixed size. This example requires that you have a class that is either directly or indirectly derived from the Control class.

protected override void SetBoundsCore(int x, int y, 
   int width, int height, BoundsSpecified specified)
   // Set a fixed height and width for the control.
   base.SetBoundsCore(x, y, 150, 75, specified);
