Incorrect Search results from a dataview. Advice please.

Hello All, I am having a problem using a search function within a dataview. My sample data was 3 names then 5.

First set was:
A smith
b smith
c smith

then i added:
d smith
e smith

(I was Searching by last name criteria)
I discoverd that my searching was taking me to the middle record of the search instead of the first record??
on my first test i was going to Record "B smith" as my starting record in my form for the search then when i added the other two then "C smith" became my starting record from my search. I am unsure what is occurring and any insight would be apreciated.

below is included my actual code...

VB Code:

Dim objDataView As DataView    
//
*
*
*
*
//
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
        Dim storeRecordPosition As Integer
        selectCriteria()
        storeRecordPosition = objDataView.Find(txtSearchCriteria.Text)
 
        If storeRecordPosition = -1 Then
            StatusBar1.Text = "Record Not Found"
        Else
            StatusBar1.Text = "Record Found"
            objCurrencyManager.Position = storeRecordPosition
        End If
    End Sub
 
 
 
 
    Private Sub selectCriteria()
        Select Case cboCriteria.SelectedIndex
            Case 0 'First Name
                objDataView.Sort = "FirstName"
            Case 1 'Last Name
                objDataView.Sort = "LastName"
            Case 2 'State
                objDataView.Sort = "State"
            Case 3 'Zip
                objDataView.Sort = "Zip"
        End Select
        StatusBar1.Text = "Sorted by " & cboCriteria.SelectedItem
    End Sub
