iterate through items in a comobox to match values

[mfaisalwarraich]

Hello,

I am trying to match the values of a combo box which are typed inside a combo box with the comb box items, which are bind to a datasource. i can see the items in the combo box and if i get the selecteditem its working fine means nothing is wrong with the connection and other things.

but when im trying to match the values im getting this error:

System.Data.Dat aRowView

and this error continues to display equal to the number of rows inside table. im using the following code:

Public Class admForm
    Dim itm As Object
    Dim result As String

    Private Sub admForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the 'admDataSet.tblAdm' table. You can move, or remove it, as needed.
        Me.TblAdmTableAdapter.Fill(Me.admDataSet.tblAdm)

    End Sub

    Private Sub cboAdm_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboAdm.LostFocus

        For Each itm As Object In cboAdm.Items
            result = itm.ToString()
            If result <> Me.cboAdm.Text Then
                MsgBox(result)
            End If
        Next

    End Sub
End Class

i have already set the display member of the combo box. everything is done from the property sheet using visual studio. i just want to match the text against the items of the combo box. for example in pseudo code


if comboBox.text <> combobox.items. item then
''add into the database

end if

here i just need to check if the typed values are already in the combo box's items collection. please tell me how i can check this.

thanx

now im using a different approach by filling in the items into the combobox. here is the code:

Public Class admForm
    Dim itm As Object
    Dim result As String
    Dim ds As DataSet
    Dim dt As New DataTable

    Private Sub admForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the 'admDataSet.tblAdm' table. You can move, or remove it, as needed.
        Me.TblAdmTableAdapter.Fill(Me.admDataSet.tblAdm)
        dt = admDataSet.tblAdm
        For Each s As String In dt.Rows.Item(0).Item("fruit")
        ComboBox1.Items.Add(s)
        Next
    End Sub
 
 End Class

the above code fill the comobox with the following value:
a
p
p
l
e

because the first row in the fruit column is "apple". please tell me how i can fill the combobox with the column values.
thanx
