Validation again

[AlexMaslakov]

The page contains some TextFields and ComboBoxes and a button (named "Button Submit") . Some of TextFields allow empty values, others don't. There is no FormPanel on the page.

I understand I have to validate manually each of these controls. But I don't know how I can make the "Button Submit" disabled if any of them is not valid.

Hi,

Well, you should use AfterRender listener of all fields to initially set up disabled state of the submit button.

To change a state of the fly, please use Change event of all fields.

Why don't you use FormPanel?

[AlexMaslakov]

'Cause FormPanel can't contain user controls and has some limitations.

Ok, thanks for the update.

FormPanel can contains another containers and those containers can use Content with user control
