How to format unbound gridview column

Is is an unbound column.

I am doing everything by code filling datasets,etc.. When I hit an apply butting in fills the gridview.  I don't see where I can use DataFormatString="{0:dd-MM-yyyy}" since the columns are not bound.  

    Protected Sub btnApplyFilters_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnApply.Click
        Select Case Me.ddlTargetField.Text
            Case "All"
                Me.FillByAll()
                Me.GridView1.DataSource = dsAll.Tables(0)
                Me.GridView1.DataBind()
                SetDataGridSettings()
        End Select
    End Sub
 
Protected Sub FillByAll()
        conTracking.ConnectionString = strConnection
 
        Dim sSelect As String = _
        "SELECT sID, sLogonDate, sLogonTime, sLogonUser, sLogonComputer," & _
        "sLogonType, sLogonIP, sLogonMAC, sLogoffDate, sLogoffTime, sFalsePos " & _
        "FROM tblUserTracking ORDER BY sLogonDate, sLogonTime"
        Dim cmdAll As New OleDbCommand(sSelect, conTracking)
 
        daAll.SelectCommand = cmdAll
        Dim cbAll As New OleDbCommandBuilder(daAll)
 
        Try
            conTracking.Open()
            dsAll.Clear()
            daAll.Fill(dsAll, "tblUserTracking")
        Catch ex As OleDbException
            MsgBox(ex.Message, , "OLEDB Error")
        Finally
            conTracking.Close()
        End Try

havent you defined your gridview in the aspx page
if yes then share that piece of code and we will try to help you out

    <asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333"
                        GridLines="None" Height="23px" Width="100%">
                        <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
                        <RowStyle BackColor="#F7F6F3" Font-Names="Verdana" Font-Size="Smaller" ForeColor="#333333" />
                        <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
                        <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
                        <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" Font-Names="Verdana" Font-Size="Smaller"
                            ForeColor="White" />
                        <EditRowStyle BackColor="#999999" />
                        <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
    </asp:GridView>

why dont you define some bound columns in your gridview so that you can fix the way you want to show your data and also format in the aspx page using the dataformatstring property
if i see your query you will like to format LogOnDate, LogonTime, Mac, Logoffdate, logofftime and it makes a lot of sense to add bound columns to your grid

I have multiple queries.  One query shows all records one shows current logons.  See Snippet.  How am I going to be able to do these queries if the data is bound?

>>>How do you format an unbound column (datetime field) in a gridview as just the date?
Is the GridView working ok without considering the format of the datetime field?

Yes it was.  I figured it out.  Thanks for you help.
