Hi,

I use an ultrawingrid to enter some data. I have two kind of validations : some validations specific to fields and a validation on the row, which depends upon combination of several fields.

My problem : when the row is not valid, I want to keep the user in the row to force him to make it valid, else delete the row. How can I do that ?

For cell validation, I put my code in "BeforeExitEditMode" event and if not valid, e.Cancel = true. This keep the focus in the cell until changes or Escape. I want to have the same behavior but for the row.

First try : using "BeforeRowUpdate". This works nice for validation, but when doing e.cancel = true, the invalid row disapears and the user have to re-enter it from scratch.

Second try : using "BeforeRowDeactivate ". This works nice for validation, but doing e.cancel = true does nothing. The user can go outside the row, the "AfterRowUpdate" fired and the invalid row is saved to the database.

Third try : using "BeforeRowDeactivate " and code to keep the focus in the row setting the suspected invalid cell in edit mode. This works nice for validation, but focus goes out of the row immediatly.

I attached the source code. Some lines are commented for test purpose.

Thank you.
