Hello,

Im currently using the code below to display 4 columns of information. I now want to add a 5th column which will display either a pdf, doc or xls logo depending on the filetype.
How can i adjust my code to do this?
' create a data adapter and a datasource

    Private Sub RetrieveNoticeboard()
 

        Dim dbSourceNew = ConfigurationManager.AppSettings("dbSource")

        Dim objConnection As New SqlConnection("Persist Security Info=False;Initial Catalog=" & _

        "myo;Data Source=" + dbSourceNew + ";User Id=sa;Password=azTbyRqX7c11Q8ZY")

        Dim noticeAdapter As New SqlDataAdapter("SELECT notice_id,notice_date,notice_type,notice_summary" & _

        " FROM noticeboard", objConnection)

        Dim noticeDT As New DataTable("notice")
 

        noticeAdapter.Fill(noticeDT)

        grdNotice.DataSource = noticeDT
 

    End Sub
 
 
 
 
 
 
 
 
 
 

   Private Sub noticeBoard_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 
 

        ' list the clients in the datagrid

        RetrieveNoticeboard()
 

        ' setup column headers

        grdNotice.Columns(0).HeaderText = ""

        grdNotice.Columns(0).Visible = False

        grdNotice.Columns(1).HeaderText = "Date"

        grdNotice.Columns(2).HeaderText = "Type"

        grdNotice.Columns(3).HeaderText = "Summary"

        grdNotice.Columns(3).AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells

        grdNotice.Columns(3).DefaultCellStyle.WrapMode = DataGridViewTriState.True

        grdNotice.Columns(4).HeaderText = "File"
 
 

        ' Update label with number of records

        numRows = grdNotice.BindingContext(grdNotice.DataSource, grdNotice.DataMember).Count

        noticeNo.Text = numRows
 
 

    End Sub

End Class
