Hi All,

               I m using Visual Studio 2005 and my language is VB.NET. I need to fill a combo box with the name of countries. I want to display the name of the country within the combo. and i also want to keep the code of the country with each name item.

Now i am aware that with visual basic 6.0. There is an option available for combo box named ITEMDATA. So that i can put an integer value with each item. But i can see this attributes has been terminated in VS.NET 2005.

but i am not aware that if any altervative has been provided in Visual studio.NET or if i want to do the same thing in VS.NET 2005. how i can do it. any help will be highly appreciated.

                       Tayyab.

Hello Tayyab

Well if u want to bind your combobox with countryname which is a string and some Integer that is code of country.
You can do it with
some class like this


Option Strict On
Option Explicit On

Public Class clsListItem
    Private mValue As String ' Stores a named description of the item
    Private mID As Long ' Stores a primary key to the record

    Public Sub New(ByVal strValue As String, ByVal intID As Long, Optional ByVal intVal As Long = 0)
        mValue = strValue
        mID = intID

    End Sub

    Public Sub New()
        mValue = ""
        mID = 0
           End Sub

    Property ID() As Long
        Get
            Return mID
        End Get
        Set(ByVal Value As Long)
            mID = Value
        End Set
    End Property

    Property Value() As String
        Get
            Return mValue
        End Get
        Set(ByVal Value As String)
            mValue = Value
        End Set
    End Property


    Public Overrides Function ToString() As String
        Return mValue
    End Function
End Class

U can fill
your combo box one by one
like this

 comboname.Items.Add(New clsListItem(NameofCountry, countrycode))


while getting the value



 countrycode= comboname.SelectedItem.id

countryname=comboname.SelectedItem.value

My Friend,

         I am truly thankful for your time. you info is helpful. this will add the object to combo box.

But I want the way that when i will add the object to the comobo box. Country name should be displayed in combo box.

but by your suggested way. when i open the combo box. It shows the name of the object Instead of its property. But i want to have the property of object(which is name in this case) must be shown.

i hope you got my point...

                         thankful

If the data source for the combobox is not normally being used to populate objects (as is often the case), you can use the following temporary object scheme for either listboxes or comboboxes:

    Friend Class ListBoxItem
        Private m_Text As String
        Private m_ItemData As Integer
        Public Sub New(ByVal ThisText As String, ByVal ThisItemData As Integer)
            m_Text = ThisText
            m_ItemData = ThisItemData
        End Sub
        Public Overrides Function ToString() As String
            Return m_Text
        End Function
        Public ReadOnly Property ItemData() As Integer
            Get
                Return m_ItemData
            End Get
        End Property
    End Class

Then add a new combobox item as follows:
YourCombobox.Items.Add(New ListBoxItem(sometext, someint))

and retrieve the ItemData later:
ThisItemData = CType(YourCombobox.Items(index, ListBoxItem).ItemData
