Difference between CellvalueChanged and Cellvalidating?

Author: Narayanan          Posted Date: July 26, 2012    Category: Windows Application     Points: 40

The DataGridView.CellValidating event occurs when a cell loses input focus, enabling content validation.So, when you add a new value to the cell, the cellvalidating will not get the new value you've entered, but an old value. Because the new value hasn't been committed.
DataGridView.CellValueChanged: Occurs when a cell loses input focus, enabling content validation.
The DataGridView.CellValueChanged event occurs when the user-specified value is committed, which typically occurs when focus leaves the cell.
This event may get the new value when you leave to edit the current cell in your DataGridView. And it will not get an empty string if you enter some characters in the cell.

How's anchoring different from docking?

Author: RamaSubbaReddy          Posted Date: September 06, 2010    Category: Windows Application     Points: 10

Anchoring treats the component as having the absolute size and adjusts its location relative to the parent form. Docking treats the component location as absolute and disregards the component size. So if a status bar must always be at the bottom no matter what, use docking. If a button should be on the top right, but change its position with the form being resized, use anchoring.
