You can use a TemplateField

<asp:TemplateField HeaderText="FilePath" SortExpression="FilePath">
    <EditItemTemplate>
        <asp:FileUpload id="FileUploadControl" runat="server" />
        <asp:Button runat="server" id="UploadButton" text="Upload" onclick="UploadButton_Click" />
    </EditItemTemplate>
    <ItemTemplate>
        <asp:Label ID="filePathLabel" runat="server" Text='<%# Bind("FilePath") %>' />
    </ItemTemplate>
</asp:TemplateField>
