Join Two tables in Runbase form?

Hi

i created runbase_form and display dropdown box in that we can choose customer. i did its working fine.

But requirement is if i select particular customer in that dropdown, that related sales order details should display

Pls reply ASAP. Am new to dynamics ax and developing in Ax2009.

Thanks in Advance

Although it can be done in a dialog (controlMethodOverload is the keyword for use in a search engine), the best way is simply to create a normal form at design time instead of using a form built at run time (that’s what dialog really is).
You’ll find an example in Tutorial_RunBaseForm class and form in AOT.
