combobox in vb.net

how to hide or disable items in one combobox on the basis of selected item in another combobox in vb.net?

From stackoverflow

• Manipulate the datasource of the second combobox in the selected index changed event of the first one.

• As gerrie said , you have to make a condition in the second combobox selected indexed changed event, like so :

  Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
      If ComboBox1.SelectedValue = "my Value" Then
          ComboBox2.Visible = False
      End If
  End Sub
  

  Where "my value" is a value I have in combobox1

  Edit :

  The combobox keeps the values inserted unless you clear them. By using this line of code

  ComboBox2.Items.Clear()
  

  Or otherwise you put the values in a list like a Datatable and point the combobox datasource of that specific Datatable

  Gerrie Schenck : I think he wants the data inside Combobox2 to change.

  Cerebrus : "she" wants... ;-)

  Drahcir : Changed my answer, hope it was you needed

• i hv tried this.

  combobox2_selectedindexchange()
  if combobox2.selectedindex=0 then
   combobox1.items.add("apple")
   combobox1.items.add("mango")
  
  elseif combobox2.selectedindex=1 then
   combobox1.items.add("grapes")
   combobox1.items.add("banana")
  
  end if
  

  it is adding the items on change of index.. but it is also displaying previously added items also.. wat to do???
