That work is pretty much what has to get implemented here.

Cellvalidating in c

I think that's something that should be brought to @blink1073 's attention.

@blink1073 the widgets, in the context that @jhpedemonte is describing, and in the context of the live notebook, use the full message to look-up the cell via the message header original message id.

How to efectively validate data entry inside a Data Grid View. Late Validation: This validation is performed after the user is done entering data.

Well, after doing some research and a bit of trial and error, found out a couple of approaches. For the specific project i was working in, it was the perfect choice.

Formatted Value プロパティに編集中の値が入ります。 しかし、この Formatted Value プロパティは表示用の書式化(フォーマット)された後の値が入ってるんですよね。 たとえば、Data Grid View で列の Default Cell Style. Format を通貨("c")として定義し、初期表示の値を 0 とするどうなるでしょうか。 ユーザに表示される値は ¥0 と表示されます。ここでユーザが ¥ を残したまま新たな数値を入れると Cell Validating時は Formatted Value が ¥1000 や ¥1,000 になってしまいます。 別に、¥1000 や ¥1,000 という正しい書式なら Data Table にバインド時に勝手にCLRが面倒を見てくれるっぽいのですが、ユーザが 99¥1000 など、書式に反する値を入れると Data Err が発生してしてしまいます。 これを Cell Validating 時にどう防ぐかで結構頭を悩ましました。 最初は書式化されてない値をなんとか取得できないかと考えました。 Cell Validating 時はまだセルに値を入れる前なので、Cell.
