Hi,
I have a radcombobox in a form page:
VB code:
i want to populate the control with external module
this is the code in the module:
When i press the button the debug is good, if i control in debug mode the combox response correctly populate:
?cbxProva.Items(1).Text
"ACQUARICA DEL CAPO"
But the combobox in the page is empty...
Why?

Hi Fabio,
In order to bind your combobox using custom function as it's in your scenario, you should pass a reference to the existing RadComboBox as an input parameter to this function.
