Sharepoint 2010 - Webpart call another webpart

Question

I´m starting developing in Sharepoint2010 and I didn´t found a way to make a webpart call (execute) another webpart. What is the best way to do it?

For example, I have 2 WebParts: A e B. The webpart "A" search countries and show the result in a grid. The webpart "B" search and show cities from a country. I would like that in the "A" after searching a country I could click a button and show the cities from this country. The "click a button" in webpart "A" would execute the webpart "B". — Evandro
