Description
Internally executed while a mouse button is pressed over the surface of this grid.
You can call MouseDown programmatically in applications to simulate a mouse button down event over this grid.
Shift indicates which shift keys--SHIFT, CTRL, ALT, and CMD (only for Mac)--were down when the user pressed the mouse button.
X and Y are the pixel coordinates of the mouse pointer within the client area of the control.
A control calls MouseDown in response to any of mouse-down messages, decoding the message parameters into the shift-key state and position, which it passes in the Shift, X, and Y parameters, respectively.
Note: Override the protected MouseDown method to provide other responses when a mouse button is down while the cursor is over the control.
