Partial Public Class WebForm1
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim adventureContext = New adventureWorks()
Dim original_employee = (From employee In adventureContext.Employees Select employee.Title)
Dim distinct_employee = (From employee In adventureContext.Employees Select employee.Title).Distinct()
GridView1.DataSource = distinct_employee
GridView2.DataSource = original_employee
Catch ex As Exception
And here's the compared result of two queries.
