| Thanks for your respones Aussie,
|
| The problems is that you didn't set the DisplayMember or ValueMember to
the
| correct string name of the Property you want to bind. Here is a simple
| example which bind a combobox to an Array of custom class objects:
|
| ======custom class==========
| Public Class CustomerClass
| Private _id As Long
| Private _name As String
| Private _level As Integer
|
| Public Sub New()
|
| End Sub
|
| Public Sub New(ByVal id As Long, ByVal name As String, ByVal level As
| Integer)
| _id = id
| _name = name
| _level = level
|
| End Sub
|
| Public Property ID() As Long
| Get
| Return _id
| End Get
|
| Set(ByVal Value As Long)
| _id = Value
| End Set
| End Property
|
| Public Property Name() As String
| Get
| Return _name
| End Get
| Set(ByVal Value As String)
| _name = Value
| End Set
| End Property
|
| Public Property Level() As Integer
| Get
| Return _level
| End Get
| Set(ByVal Value As Integer)
| _level = Value
| End Set
| End Property
| End Class
| ==================================
|
|
|
| =========databinding===========
| Private Sub InputForm_Load(ByVal sender As System.Object, ByVal e As
| System.EventArgs) Handles MyBase.Load
|
| Bind_cbCustomer()
|
| End Sub
|
| Private Sub Bind_cbCustomer()
|
| Dim customers() As CustomerClass
| ReDim customers(15)
|
|
| Dim i As Integer
|
| For i = 1 To customers.Length
|
| Dim cu As New CustomerClass
| cu.ID = i
| cu.Name = "Name_" & i
| cu.Level = i Mod 5
|
| customers(i - 1) = cu
| Next
|
|
| cbCustomers.DisplayMember = "Name"
| cbCustomers.ValueMember = "ID"
| cbCustomers.DataSource = customers
|
|
| End Sub
| ========================
|
| Hope helps. Thanks,

| | Hi,
| |
| | The following code :
| |
| | For Each pRow In dsName.Tables("Property").Rows
| |
| | Dim oObject As New clsProperty
| |
| | oObject.intPropertyId = pRow("Property_ID")
| |
| | oObject.strProperty_Address1 =
DBTextToString(pRow("Property_address1"))
| & "
| | " & DBTextToString(pRow("PostCode"))
| |
| | oObject.strPropertyPrice = DBTextToString(pRow("Property_Price"))
| |
| | cboProperty.DisplayMember = oObject.strProperty_Address1
| |
| | cboProperty.Items.Add(oObject)
| |
| | Next
| |
| |
| | Produces a drop down list that contains 'ProjectName.ClassName'
| |
| | What am I doing wrong here ?
