Net first came out, someone would have noticed and said, "We need to correct this." I'm not sure of how to place a bug report wtih MS without paying for it (or using up a limited number of free support requests).

The information I see Microsoft's web site on support requests doesn't say anything about "no charge if due to a bug in Microsoft software;" I guess they're big enough they think they can get away with that.

from day to month, or from a value cell to a place holder cell) and committal of the whole thing occurs when focus moves out of the control.

But the committal of the current cell is not forced before the committal of the whole thing so, if the cell concerned was not "full", the change to it happens too late for the full committal.

when current row changes so that the whole record would be sent to the datatable, or before an .

End Current Edit is called), or at least to some "next cell" code.

I can understand why the event doesn't fire as soon as the digit is entered, since one might be entering two digits.

2 digits in a cell which will take 2 digits) or when a new cell is moved to (e.g.

What I mean by the latter is something on these lines.

In the datagrid's Current Cell Changed Event (pseudo code) Static Check Date As Boolean = False If Check Date Then 'go back and check the date in the cell just left End If If currentcolumn is datecolumn then Check Date = True Else Check Date = False End If Roger Thanks for your testing, Roger.

Is my only solution user education to do one of those things, or is there another way to get the value changed before Validating/Commit fires? The control is, I reckon, composed of various sub-controls.

Try using a custom format with a single marker for the day and the month. For me, that fires value changed with a single digit entry before validation fires. Using the analogy of a datagrid's rows, the movement from cell to cell within a row "commits" an edit to the cell that has just been left, and any move to a new row both "commits" the cell that has just been left and then "commits" the whole row that has just been left.
