Datagridview rowvalidating example

The Cell Validating and Cell Validated events will be fired when the edited cell is losing the focus.You may take a look at our online documentation for further reference on the validating events and the way a validation can be performed.Here I'm with this trying to figure out how to enable a button I disabled and the right place for me was like the Row Validated but as I saw with the version 419 today, The Row Validated is called only once the Grid View loose focus however it's called Row Validated hence it should be fired when the row is validated. I am afraid I am not able to understand your scenario very well. Hi, I have been working with the validation on my Rad Grid View. I don't want to use cell validation but row validation is occurring with every cell edit.Could you strip only a part of your code and send it as a small example to allow us looking into this issue?In order to be able to send us your project, you have to open a new support ticket.For example if I have a filter set to name = bob and attempt to add a row but specify name = bill i will get the Index Out Of Range Exception.The exception occurs when i try and access the datagridview.currentrow property in my rowvalidating event handler, or alternatively datagridview.rows(e.rowindex).

I can catch the exception and it would seem that the row is successfully added to the datagridview however I'd like to know what it is that is causing this behavior.

I would like to see something like the Validates On Data Errors property contain an option for On Row Focus Lost or similar meaningful option.

I have looked around but in this case cannot seem to find a way of achieving what I want.

I have informed my employer that hitting the Tab key would be more natural to move to the next column but they are firm on making the Enter key do this.

When they are in the 2nd or 3rd last column (depending on whether Debit or Credit value entered) and hit Enter, the behaviour they wish to see the Rad Grid View exhibit is to create a new line, give the newline focus and perform validation on the row that has just been vacated (lost focus).
