Hi all,

I have a generic toolbar with buttons to create records, delete records, next record, previous record etc.

When the user is in a datasource that can only be queried, the buttons to create and delete records should be disabled. Similar situations exist for all buttons.

So i need to turn on and off buttons. Is that possible? How?

If yes, is there an API to change the icon for the button? I would like to grey out the button so the user sees that the button has no use.

I have found api_component.setvisible, but i do not want to totally hide the buttons because when the user navigates through the application, continuously buttons will appear and disappear.

Kind regards, Jan Willem

Hi Jan Willem,

Keep in mind that if you disable the save button by default and the user opens a form and just edit 1 field without leaving the field it looks like he cannot save the changes because the save button is still disabled... The save actually works by clicking this disabled save button, because the valueChanged event triggers and enables the button, so the click works, but for the user this is not intuitive (clicking a disabled save button...)

For this reason i chose to hve the save button alsways enabled, and give a message in the status bar that there are no changes to save when he clicks the button when there are no changes.

Best, Michiel

Hi Jan,

To achieve your request, you can use api_component.setEnable API. You can turn off a button by setting its enabled property to N and turn it on by setting its enabled property to Y via this API.

This API also automatically greys out the button and its icon, I guess it will meet your need. However, you can always use api_component.setIcon API to change the icon of a component.
