title: Cell Value Changing Event ,c#
body: <p>I have a DataGridView in which there are 3 columns; Quantity, Rate and Amount.<br>
  The DataGridView is Editable. When I enter a value in the Rate Column then immediately the value should be changed in Amount.  </p>
  
  <pre><code>Amount=Qty*rate
  </code></pre>
  
  <p>It is happening, but when I click on any other cell, I want that when I enter any value in Rate it should be multiplied with Quantity and be reflected immediately in Amount without changing the cell.</p>
