Hello group, I’m trying to handle the various types of errors from the user: I have problems in the row:
if ComboBoxNomiFornitori.RowTagAt(ComboBoxNomiFornitori.SelectedRowIndex).IsNull then
When the value in the combobox is there, I pass the ID to rowtag, when it is not there I have the error.
error: OutOfBoundsException
