RE: [flexcoders] Re: Flex 1.5 - n checkboxes
A high level comment that may help you to put
your problem and solution in a different light
In our work with Flex I have found using a
repeater to be a bad smell worth looking in to. Usually,
replacing a repeater with a List and CellRenderer cleans things up immensely and
enables componentization of your solution including easier event handling and
data binding. Remember that a List is not necessarily a ComboBox or a DataGrid.
We have found that many UI programming tasks decompose well into a List and
CellRenderer.

1.5 - n checkboxes
No, my requirements are
simple. An Edit User panel with checkboxes for all the roles the
user has.
I have the check boxes rendering as follows
mx:Repeater
id=rolesList dataProvider={allroles}
mx:CheckBox
id=role label={rolesList.currentItem}
selected={user.hasRole(rolesList.currentItem)} /
/mx:Repeater
Now, I need to submit the form, and call user.setRoles() with an array of the
the checked roles. Right now there roles are just strings, but they should
probably be Role objects.
Presumably I will need a submit handler that iterates over the checkboxes
looking at their selected state and building the array of checked ones. I don't
know how to do that yet, but I'm sure I can figure it out.
It would be nifty if there was a more automatic way to do this.
Thanks,
Richard

Hi Richard,
I recently completed a project in which we had to
dynamically build
form selection elements based on different control
types (eg.
checkboxes, radio buttons, etc...). The data
model we worked with
provided us with the string name of the control
type to use, and the
appropriate data structure to populate the control
type(s). Solution
I came up with was to (as you mention you might
have to do) create the
form elements using actionscript, more
specifically the createChild
method. I created a custom instance of each
control type, and added
some additional properties to it, the most
important being the data
property it needed to affect. Inside the
custom control, I had my
change event directly modify the data property
that was passed in.
Because the reference was passed in, this
essentially bound that
change to the data model it came from.
Problem solved.
Your requirements may be slightly different as it
sounds like you
already know what type of control you need to
render. In this case, I
would imagine you could use a repeater tag and
have it's children be
the custom check box you're creating,
and pass in the object
property reference that needs to be changed.
Hope this helps you...

Re: [flexcoders] Re: Flex 1.5 - n checkboxes
I agree; wrapping my head around Repeater has been
very tough; it's so much easier to create either a cellRenderer that does what
you want in a List, or just use createChild/destroyChild with a
VBox.

property it needed to affect. Inside the
custom control, I had my
change event directly modify the data property
that was passed in.
Because the reference was passed in, this
essentially bound that
change to the data model it came from.
Problem solved.
Your requirements may be slightly different as it
sounds like you
already know what type of control you need to
render. In this case, I
would imagine you could use a repeater tag and
have it's children be
the custom check box you're creating,
and pass in the object
property reference that needs to be changed.
Hope this helps you...

Is there a slick way to bind a variable number of
checkboxes to
an array
of value objects in a data model?
Example: user has an array of roles. Display a list of
checkboxes
I see how to use repeaters to render the checkboxes,
but I'm
unclear on
the best way to capture the user selections.
Thanks

[flexcoders] Re: Flex 1.5 - n checkboxes
Hi Richard, I recently completed a project in which we had to dynamically build form selection elements based on different control types (eg. checkboxes, radio buttons, etc...). The data model we worked with provided us with the string name of the control type to use, and the appropriate data structure to populate the control type(s). Solution I came up with was to (as you mention you might have to do) create the form elements using actionscript, more specifically the createChild method. I created a custom instance of each control type, and added some additional properties to it, the most important being the data property it needed to affect. Inside the custom control, I had my change event directly modify the data property that was passed in. Because the reference was passed in, this essentially bound that change to the data model it came from. Problem solved. Your requirements may be slightly different as it sounds like you already know what type of control you need to render. In this case, I would imagine you could use a repeater tag and have it's children be the custom check box you're creating, and pass in the object property reference that needs to be changed.
