identity id and exclusive group Radio Button created dynamically from a database

Pisko

Hi everyone,

I made a little app which read the possible answers of a quiz from a database.

The first problem is that I don't know how to definite the button id if i create them dynamically so I cannot identify which buttons are pressed to save the answers in the database.

Another problem is that I cannot create Exclusive Groups dynamically.

I hope some you can help me. Thank you all and sorry for my bad English.

Hi @Pisko and Welcome,

The first problem is that I don't know how to definite the button id if i create them dynamically so I cannot identify which buttons are pressed to save the answers in the database.

Unfortunately you cant assign an id for dynamically created items. Check this for more details.

Another problem is that I cannot create Exclusive Groups dynamically.

I think you can use a ExclusiveGroup here.
