Smnehal not sure what your problem is but… comboBox?, there is no control called this way on the toolbox. For options to be displayed just use a textbox which SourceExpr property is a field of DataType “Option”, automatically a combobox is displayed with the options.
To use another field that depends of the first Option field, maybe it’s enough with a Flowfield… for example take a look to the Sales Line table, where the No. field depends of the value of Type field.
Are you telling about Payment line on Invoice form as an example of what you want to accomplish or… what?
Combobox doesn’t exists in Navision, but on the invoice form many field (payment method and payment terms included) work as if they were. This is accomplished by defining a table relation on the invoice header TABLE (not on the form) for the fields you want to be displayed that way. Navision does the rest by itself.
Combobox are not in Navision, however in some cases like invoices you can accomplish them by defining a table relation on the invoice header TABLE (not on the form) for the fields you want to be displayed that way.After that Navision takes the control of it own, i hope that will be benificial for you, if you have any queries please feel free to contact me at my email id firstname.lastname@example.org .
