            Dim FileName As String = BookingNumber + "_WRH_" + (i.ToString()) + PathName
            hpf.SaveAs(Server.MapPath("~/UploadedImages\") & FileName)


            objWHParent.WHImageTabList.ToList().Item(i).FilePath = FileName

您需要在gridview上添加图像控件，并从您的数据源中提供URL。请参阅以下代码以供参考：

<asp:GridView ID="gvFolder"  runat="server" AutoGenerateColumns="False">
<Columns>
<asp:BoundField HeaderText = "Image Name" DataField="ImageName" />
<asp:TemplateField HeaderText="Image">
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("ImageURL") %>'Height="150px" Width="150px"/>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

如何从根目录中的文件夹中显示上传的图像文件？
