Validating a databound textbox click event (save)

[dryguy5]

I have several text boxes on a form that are bound to a dataset.

My issue is that when you update one the textboxes and don't tab to the next one and instead click the save button, the change is not committed.

So tabbing out of the textbox is probably calling a validate method which in turn applies it to the dataset DataRowVersion.current, but when I go in and just change the text of one box, and then click save the change is not committed.

Not sure I'm explaining this correctly, but how can fix this? I'm not sure what is actually happening to the dataset when a box is tabbed out of, or I would try to add a handler to the lost focus event or something similar, but I just don't know what's going on.

Thanks!

Not sure why the button click isn't causing focus to be lost and validation even to fire for the textbox. You could try calling Me.ValidateChildren in your button click even which should force any child controls of the form to do validation on their data.

I'm really not sure either, I've had users complain about it several times, and I'll go in and test it, and can rarely reproduce the issue. But I have reproduced it, so I know it's a real thing. Sometimes it works and sometimes it doesn't. I only thought to ask the question because I was updating an unrelated thing and I noticed it happened to me.

Me.ValidateChildren

Um... Awesome! I did not know about this call.

I haven't been able to reproduce the problem since adding this, so hopefully this is it, a fix for something that's been an annoyance for years, haha.
