Re: [flexcoders] Dynamic Checkboxes

[Phil Marston]

Personally, and I'm no expert, my first thought would be to look at using the checkBoxes as an itemRenderer in one of the List based components you would have their properties determined by the dataProvider for the List and when you make changes to the dataProvider the checkBoxes as itemRenderers would reflect that - I think ;-)   Have a look at the use of the checkboxes in the Restaurant Finder example that comes with Flex 2.0 - I suspect it might have something to take you in a useful direction. Sorry I can't be more specific, I'm learning too! Phil jobforkomputerman wrote: I am running into a bit of a problem here and could use a nudge to get going again. My problem is that I have a list of Users in a left hand panel of a HBox canvas. In the right hand panel I want to have a bunch of Security Roles the User can be assigned to. I want the right hand panel to show all of the Security Roles that are available, in a listing of checkboxes, but not have any of the boxes checked until I select a User from the list in the left hand panel. When I select a User from the list I want to have a check mark placed in all the boxes that the User is currently associated to. I.E. I have 4 security roles (Sec_Role_1, Sec_Role_2, Sec_Role_3, and Sec_Role_4) and User_A is associated to Sec_Role_2 and Sec_Role_3. When I select User_A from the list in the left hand panel I want a check to appear in the checkbox for Sec_Role_2 and Sec_Role_3 but not Sec_Role_1 or Sec_Role_4. Then I want to be able to make changes to the Security Role to User association (I.E. remove the check from Sec_Role_2 and put a check on Sec_Role_1), hit a button, and save the results back to my database. My questions are as follows. First of all I am not really sure if I should try to place the checkboxes inside a repeater or inside of a data grid using a rendering of a component inside a data grid. The second problem I am having is the list of Security Roles is created by one query (because the number of Security Roles can change) and the association between Security Roles and Users is created by another query. How do I first create the checkboxes and then loop through the second query to check or uncheck the checkboxes? Or do I need to write my CFC so it returns all Security Roless for each User along with if there is an association between the two or not? Any ideas on how I would accomplish this??? I've seen plenty of examples on how you use checkboxes to have forms do things but I haven't seen an example where the checkbox is reflecting data already in a database! Thanks in advance for any help you can offer!!! Have an Ordinary Day...
