Content (required):

Hi experts,

I have a Combobox (Many) in my Web App and the user wants to copy a list of values from a column from an excel doc, paste those values in the Combobox (Many) control and the combobox should solve those values and show them in the combobox as if the user had selected them manually.

Is there a way to do this that does not required customization? Is there a property that should be enabled?

Thanks in advance!
