System.Windows.Forms.Design.ParentControlDesigner.OnMouseDragBegin Method

Called in response to the left mouse button being pressed and held while over the component.

Syntax

protected override void OnMouseDragBegin (int x, int y)

Parameters

x
The x-coordinate of the mouse in screen coordinates.
y
The y-coordinate of the mouse in screen coordinates.

Remarks

This method is called in response to the left mouse button being pressed on a component. The designer overrides the base form of this method to provide a "lasso" selection mechanism for components within the control.

Note:

You can pass a point in screen coordinates to the System.Windows.Forms.Control.PointToClient(System.Drawing.Point) method of the System.Windows.Forms.Control class to obtain the coordinates of the point relative to the upper-left corner of the control.
