The ComboBox list is driven by a dataProvider, which can be a collection of complex objects. You can specify the labelField to be whatever property in the dataProvider item object you want.
When an option is selected, you can access the entire selected item by using ComboBox.selectedItem. You can then access whatever property you want. The problem is that the standard ComboBox only allows setting selectedIndex. So if there is a value in the mainDG item that you need to have the ComboBox display, you have to loop through the CBO dataProvider, and compare that value to the corresponding property in the ComboBox dataProvider item. When you find a match, you can use the loop index to set the selectedIndex. To make this happen in a dataProvider, you have to run that select search loop from the set data or commitProperties override. I have posted an example of this recently, and ther is a copy posted here: http://www.cflex.net/showfiledetails.cfm?ChannelID=1&Object=File&objectI D=767 That example allows for row level differences in the ComboBox dataProvider, or you can have a static list at the parentDocument level. That particular example uses simple values for the CBO dataProvider, but using a complex object should be little different.

I want the combobox to display something but onchange submit a value. so for example the combobox would display "One" but when submitted it submits "1". Now this "1" is tied to an attribute of a User Object. each row of my datagrid represents a user object and each user object has a "role_id" attribute. My combobox's dataprovider is a static list of all possible roles and i want the option with the user's "role_id" to be selected. but it cannot display the role_id, but must display the role_label. How do i do this? it probably doesnt make much sense. grrr i hate having to type this out. --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Not sure I understand.
