Logic in the Row Source Upload Images   Link   Email  
Chris Pardy 
I use these cascading combo boxes a lot... I have come up against a situation where I would like to use a series of combo boxes to filter a continuous form, using the techniques in the "Find Record" extended cut video.. But because the combo boxes in the middle of the cascade depend on the value in the upstream box I cant just use one of those as filter criteria.. is it possible to use some logic to determine: if Is not Null Combobox X then use select statement A as the row source. If isNull combobox X then use select statement B as the row source. Id love to know if this is possible and if so how to pull it off. thanks again.

Yes, you could dynamically write the SQL for the rowsource in VBA. I cover this in Access SQL Seminars and Access Search Seminar and in several Developer lessons.
