Date picker connection with different buttons for different dates


I would like to connect each date different buttons of the app. So when I pick a date with the date picker, the special button for this date should be opened. Is there any possibility to do that?

probably you like to explain a little bit more in detail what you are trying to do?
a button does not open, a button can be clicked to do something

Have you read the AI2 free online eBook   http://appinventor.mit.edu/explore/ai2/tutorials.html   ... the links are at the bottom of the Web page.   The book 'teaches' you how to program and how to use the event handler in "Buttons."

A DatePicker can be used to set the text on  a Button.   The controls available on a DatePicker are described here:  http://ai2.appinventor.mit.edu/reference/components/userinterface.html#DatePicker 

The code to set the date as the caption on a button would go 



AfterDateSet()
Event that runs after the user chooses a Date in the dialog
in the above block.

Try some blocks, post a screen capture image of your blocks and you will get more advice if necessary.

Yes, I have read but it does not show what i want. 
Sorry, what i meant was, when I pick a date with the date picker, the special button for this date should be appeared.

I want to set the special button visible only on a date when the date is picked. I have tried many ways but to no avail.

Button1.visible=false   to hide the button;   Button1.visible=true to show the button.      I think the answer above is the correct one, your explanation is not clear.   You did not post your code.    If you want help, draw a picture of what you want; post a screen capture of the blocks you tried and someone might be able to figure out what you are thinking.

Thank you guys for your help. I have figured out and got what i wanted.

in this case, you will need only one button
