Hello Experts,
7.1.1
I'm trying to implement a simple combo-box which will show a list of values in a dropdown. This is ok and the control shows.
Now, the source data collection which contains the list of values to be shown for this dropdown can change based on another value in a another combobox dropdown. For instance, if the first combobox contains a list of countries, the second one should show cities within the selected country.
To do this, whenever the value in the first drop-down changes, I do a PropertyWatch and based on some logic I delete the collection for the second combobox and repopulate it with new values.
I tested this and the values get correctly populated in the new collection when viewed in the collection data, however in UI I get the error shown after changing the value in the first combobox
So is it not possible to change the value in the collection of a combobox once it has been populated?
As always, thanks in advance!
Kin
