SharePoint Designer is Great tool to Create Web parts , and you can easily understand its code behind and very easily you can change it according to your need/requirement.

i have created 2 web parts and they are placed on different pages, I have define the Students in one web part and in Other i need Filter its courses.

  1. Create 2 Lists (Students, Courses), In courses i have used Student as lookup column.
  2. Open SharePoint designer and open specific site .
Create First Web Part (Sender)


Step 1:
Create Page in Site Pages Library. Click on Design mode ,
