Try this code It's Quite EASY.

Or you want something else??

VB

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
        If ComboBox1.Text = "RED" Then
            TextBox1.Text = "RED SELECTED"
        End If
    End Sub
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ComboBox1.Items.Add("RED")
    End Sub

Solution 3

hope this is what u want!

in master page's window loaded sub:

private sub Window1_loaded(..........)
combobox1.items.add("Apple")
combobox1.items.add("Kiwi")
.
.
end sub

then create another function to load these items.. i will use a list here coz u may hav more than 30 items..

public function AddInList() as List(of String)

dim lst as list(of string)

for i=0 to combobox1.items.count
lst.add(combobox1.items(i))
next i

return lst

end function

Now in your sub-product page:

do this in that sub-product's loaded sub:

dim w as window1
dim myList as List(of string)=w.AddInList()

and then

for i as integer=0 to myList.count
combobox2.items.add(myList(i).toString())
next i

textbox2.text=combobox2.selectedItem()

Hope this helps!! :)

There is no Need for SQL Data and SQL Connection for this Query you can solve your problem very easly by this way

Add Data Apple,Oranges,Kiwi and Bread your Combobox and then write the
given code in SelectedIndexChanged Event of Combobox.

C#

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
     {
         textBox1.Text = comboBox1.Text;
     }
