hi bkimmelca,

i have handled this sort .. n the solution is ..

1. set update mode to - on cellchange or lost focus

2. use a  BeforeCellDeactivate event  within this validate the cell value ..

if not .. use this code to set the cell to edit mode ..

         e.Cancel = True

3. use  BeforeRowUpdate event

           and check for the cell values ..if not .

hppy coding .

I am having precisely the same issue as indicated above.  I have an add row at the top of the grid.  I am handling the BeforeCellUpdate event to validate the data in the row when it is changed (including when data in the add row is changed), and setting e.Cancel = True if the data is not valid.  However, a new, empty row is inserted into the underlying data source before any cells are updated (and therefore before "BeforeCellUpdate" is called).  What I want is for the add row not to add anything to the data source until the row is complete (i.e, when the user hits the enter key on the row), so that I can validate what is about to be entered before anything is added to the underlying data source.

I don't understand what you mean. What empty row?  

Mike, can you provide a sample code to check all the cells in the previous row?
