Combobox has a property of .Items that you populate with the things you want it to display.

Hi myanmaraladin,

You can use a nested if-else statement or a select case. Under the SelectedIndexChanged event of your combobox1 (assuming this is your list of categories) try this:

if combobox1.Text = "Action" Then
     combobox2.Items.Clear()
     combobox2.Items.Add("Action Movie 1")
     combobox2.Items.Add("Action Movie 2")
     combobox2.Items.Add("Action Movie 3")
ElseIf combobox1.Text = "Sci-Fi" Then
     combobox2.Items.Clear()
     combobox2.Items.Add("Avatar")
     combobox2.Items.Add("Transformers")
     combobox2.Items.Add("X-Men")
ElseIf combobox1.Text = "Comedy"
     combobox2.Items.Clear()
     combobox2.Items.Add("Ang Tanging Ina")
     combobox2.Items.Add("Paano Na Kaya?")
     combobox2.Items.Add("Agent X44")
End If
 

Or you can also use AddRange Method

combobox1.Items.AddRange(New Object() {"Action Movie 1", "Action Movie 2", "Action Movie 3"})
