Do you remember that you taught me how to entry data at datagridview and use Enter to move to another column or row? The first it's to capture the enter key on the datagridview to do something (in that case to change the behavior).
I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. That’s why we’re bringing professional training courses to Experts Exchange. This is perform some validation AFTER the user changes the data.
You cannot detect from the Process Cmd Key if the user have changed a value in the cell. The first it's to capture the enter key on the datagridview to do something (in that case to change the behavior).

This way you can use the build in events of the datagridview (Cell End Edit) to handle your validation.
Row Inde Why should I check column 1 when the problem happened on other column?
I am not going any where, but the fact is I am using it. You should not place any custom validation code in it. Altough I havent tested thoroughly Send Keys with Cell Validating, I did experience what you were saying only if a breakpoint is set. Anyway, it is not the best solution, I agree, but its better that doing this in Process Cmd Key event. Private Sub dgv Transaksi_Editing Contro Please see the scenario. Therefore when the current cell is not number field then we should deactivate the handler, am I right? In your example, if column index for Item Code is 0, so it will not validate it. Thus my code like below: Public Shared Sub Validate Numeric Input(By Val Hi Priest04, It works.
I just want to know whether the way I do cause the problem or not? I have try any other event to move from one cell to next cell using Enter, but I can not get solution from EE, and later jpaulino taught me to do that and so far I am happy with it except this problem.

I am giving you one code, you are returning yours.... First of all, Process Cmd Key is not a place where you would put your business logic. You would be rewriting in many applications, which could lead to a nighmare. Key Char = Nothing End Select end if End Sub If you mean this, this is not the problem. Now, we click Item Code cell which should could accept number and non number key. Key Char = Nothing End Select End Sub Then you are incorrect. Key Char = Nothing End Select end if End Sub What I used in my code are enum values, which I saw you were using in your example, so Nilai Transaksi should have value 1 and Nilai Kurs should have value 2. C = 2 Then If we use the above code then it will be the code at any form.
For that purpose events like Cell Validating, Cell End Edit and similar are used. So, the point is to create something that can be reused any time. And this is where you should have implemented the cell focus behavior, but, in this case, ONLY that. Your forgot to remove handler when it is not needed, am I right? Since the handler still active then we can not input non number key, am I right? However, this is why you should add column index validation, so it will validate only 2nd and 3rd column. If this enums should not be applied in this example, then you should replace it with the accoring ones, I cannot know the structure of your project. I want to make it public so we don't have to take care the column number.
