Textboxes are not validated after clicking in a control's background

[abeham]

It would be nice to have textboxes validating upon clicking "anywhere else". Currently you have to find another control that accepts focus.

I'm going to try this on a demo project

I played around for a while, but without success. I have found a similar question at ​stackoverflow, where the answer was "UserControl will fight you tooth and nail to avoid getting the focus."

The problem is easily reproduced by creating an empty Form and adding a sole TextBox. The event handler on the Validated event of the TextBox fires only upon closing the form. There's no other possibility to validate the TextBox (the box as dragged in from the toolbox didn't even validate on pressing Return or Enter).

This "bug" also has a consequence: When you edit the value of a parameter, click the save toolbar item and save the currently active item, it will not save the item with the parameter value that was just entered, but with the old one. The TextBox does not lose focus when a toolbar item is clicked.

To be fair though this has not yet been an issue (and is probably there since 1.1). It seems to be pretty complicated to achieve validation on "anywhere-click". The other solution would be to always provide a second control to validate the input like a button, but I'm not a big fan of this either.

Maybe we can at least fix the bug somehow by calling ​Validate() on the form before performing an action in a toolbar- or menu item, don't know yet if that will work.

Thanks abeham for your effort on this issue.

However, to be honest, I would recommend to leave this behavior as it is. It is definitively there since the first version of HL and I don't think that we had any severe difficulties because of it so far.
