change visibility of toolbar buttons failed

[Robert]

Hello,

I have the following Toolbar. Depending on conditions that are evaluated in the databound event of a formview named "fv_ProjectData", I want to enable/disable some buttons. The problem is, that the buttons aren´t updated. The databound event fires as expected and the visible properties of the toolbar buttons are set correctly. But the buttons are updated only when clicking for example another button. What settings in the Ajax Manager are necessary that the formview updates the buttons.
 
Any ideas ?

Hello Robert,

I'm afraid that I'm unable to recreate the behavior you have described locally. I have attached a small test page, please take a look and let us know if I'm missing something obvious.
