Can you please clarify what it is exactly that is in the Items collection? You have a class defined with the two properties shown above and you are adding instances of that class to the combobox?

Can you show me an example of how you are loading the combobox?

Thanks.

Yes, is class with 2 properties.

set lblAttrib1::Content to category-attributes(idx)::NAME

set cbAttrib1::ItemsSource to category-attributes(idx)::VALUES

set cbAttrib1::DisplayMemberPath to "VALUE"

set cbAttrib1::SelectedValuePath to "ID"

i want to find a specidic attribute in the combox and then set the selected value to that index.

Is this what you are looking for?

This example displays the VALUE property in the list and then allows you to set the selected item to the one that matched the ID property given.

       01 entry1 type findentry.myitems value new findentry.myitems(property ID = 3, property VALUE = "TEST1").
       01 entry2 type findentry.myitems value new findentry.myitems(property ID = 2, property VALUE = "TEST2").
       01 entry3 type findentry.myitems value new findentry.myitems(property ID = 1, property VALUE = "TEST3").
       01 mylist type ObservableCollection[Type findentry.myitems].
     
           
           set mylist to new ObservableCollection[type findentry.myitems]
           invoke mylist::Add(entry1)
           invoke mylist::Add(entry2)
           invoke mylist::Add(entry3)
           
           set Combobox1::ItemsSource to mylist
           set Combobox1::DisplayMemberPath to "VALUE"
           set Combobox1::SelectedValuePath to "ID"
           
           set Combobox1::SelectedValue to 1

       end method.
       end class.
       class-id findentry.myitems.
       working-storage section.
       01 valueid        pic 99999999 value 0 property as "ID".
       01 attributevalue pic x(30) value spaces property as "VALUE".

       end class.

basically im looking how to do

ComboBox.FindString(String) Returns the index of the first item in the ComboBox that starts with the specified string.

But I think it will be better if I use Combobox::SelectedVaue as Sugested, Just gotta change the logic in my code.
