title: DevExpress GridView PostEditor
body: <p>I have a grid control with unbound columns in it.
  The question is, everytime I change a cell value (I am using a repository item) I immediately call the gridview.PostEditor() method so that it would right away update the grid data which requires to be updated everytime I change a specific cell. Keep in mind  that I am using the PostEditor() method so that I dont have to lose the focus on a cell first to update the gridview. Anyway, calling the PostEditor() will update my grid (which works fine) and still have the reposiroty item open, a repositoty item spin edit control to be exact, but the thing is if I hit a numeric key, It will discard the old value and replace it with the new one. I don't want it to behave like this. I want it so if the old value is 10.00 and I press the "0" key it will change the value to a "100.00" not back to "0.00". </p>
  
  <p>Please help! </p>
  
  <p>Thanks! :)</p>
