<asp:GridView ID="gvAttach" runat="server" AutoGenerateColumns="False" DataKeyNames="projectID">
<Columns>
                                                
<asp:TemplateField HeaderText="Download">
<ItemTemplate>
<a href="<%#Eval("fileLocation")%>"> <%#Eval("fileName")%></a>
</ItemTemplate>
</asp:TemplateField>
                                                
<asp:BoundField DataField="fileDesc" HeaderText="Description" SortExpression="fileDesc" />
<asp:BoundField DataField="contentType" HeaderText="File Type" SortExpression="contentType" />
<asp:BoundField DataField="fileSize" HeaderText="Size" SortExpression="fileSize" />

</Columns>
</asp:GridView>

    private void BindData()
    {
        try
        {
            string strDb = Server.MapPath("KMSSP.accdb");
            string strCon = "Provider=Microsoft.Ace.OLEDB.12.0; Data Source=" + strDb + "; Persist Security Info=False";
            string strSql = "SELECT * FROM Attach";
            OleDbDataAdapter da = new OleDbDataAdapter(strSql, strCon);
            DataTable table = new DataTable();

            da.Fill(table);

            gvAttach.DataSource = table;
            gvAttach.DataBind();
        }
        catch (Exception ex)
        {
            Helpers.ShowMessageBox01(ex.Source + " ; " + ex.Message + "<br/>" + ex.StackTrace);
        }
    }
