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... Brendan --- In [email protected], Richard Rodseth <[EMAIL PROTECTED]> wrote: > > Yes, as I mentioned, I am using the repeater tag.
