I am developing a Sharepoint Web Part, that connects to some external resources. I am fully familiary with the programming aspects of Web Parts, however, I want to give my customer some flexibilty around the configuration of the Web Part. For example, lets say I need to connect to a database, I would like for there to be a way to configure the web part to connect to a certain dabase, without hardcoding.
I assume I could use xml configuration files, which is all fine, but I was wondering if there is a more GUI driven way to configure web parts in Sharepoint?
Hope that makes sense!
