[RESOLVED] array to combobox

hey all...

a quick question regarding binding an array to comboboxes.

i have mutilple comboboxes which will contain the hours and minutes

so i've create 2 arrays, one containing the hours and one containing the minutes

Code:

Dim l_hours As String() = {"00", "01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23"}



so i want to assign the hours to several comboboxes. I do this by:
Code:

cbo1.DataSource = l_hours
cbo1.SelectedIndex = -1
cbo2.DataSource = l_hours
cbo2.SelectedIndex = -1


however whatever value i select in cbo1 it is set in cbo2 aswell.
eg: i select 10 from the dropdown in cbo1, when this is selected 10 becomes the selected value in cbo2.

can someone explain this to me... there something im not doing right here

I realy don't know why it does that but i guess the reason is that you bind the same object to the two comboboxes. If you don't want it hapen then you need to have two diferent array objects bind to the controls.

vb Code:

Public Class Form1
    Dim l_hours1() As String = {"00", "01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23"}
    Dim l_hours2(l_hours1.Length - 1) As String
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.ComboBox1.DataSource = l_hours1
        Me.ComboBox1.SelectedIndex = -1
        Array.Copy(l_hours1, l_hours2, l_hours1.Length)
        Me.ComboBox2.DataSource = l_hours2
        Me.ComboBox2.SelectedIndex = -1
    End Sub
End Class

You will need to 'reset' the binding context or better said, assign a different binding manager to each combobox:

Code:

---

        cbo1.BindingContext = New BindingContext()
        cbo1.DataSource = l_hours

        cbo2.BindingContext = New BindingContext()
        cbo2.DataSource = l_hours

---

Or you can simply use AddRange.

Code:

---

        cbo1.Items.AddRange(l_hours)
        cbo1.SelectedIndex = -1

        cbo2.Items.AddRange(l_hours)
        cbo2.SelectedIndex = -1

---

the first one works perfectly as im doing this on the compact framework
