Asp.net 数据和图像填充为两行。我想把它们捆成一行

我要第二次问这个问题。我要说清楚，这样你可以帮我：）好的，我们开始吧

我有一个注册程序。我把这个过程分成两页。第一页仅用于“个人信息”。然后，当我点击下一步按钮，下一页将出现（postbackURL）这个页面是“上传照片”页面。他们工作得很好！数据和图像显示在我的gridview控件上。但我的问题是：如下图所示。数据填充为两行！我希望它们只出现在一行中！我认为问题在于第1页的数据库没有继续。这就是为什么当我在第2页上传图像时，数据库会创建另一条记录。嗯……有什么问题：）我不知道怎么做。请帮忙

下表所示数据仅为虚拟数据。请不要当真。

以下是PersonalINFO.aspx页面的插入/更新代码：

您需要将ID从个人信息页面传递到上传页面（可能通过查询字符串）

然后，图像更新的查询应该是和update query，见下文

cmd.CommandText = "UPDATE PendingRecords SET [Image] = @Image WHERE ID = @ID";

现在将根据需要传入ID参数

如果参数在查询字符串中（/UploadPhoto.aspx？id=60）

错误：）“异常详细信息：System.Data.OleDb.OLEDBEException:没有为一个或多个必需参数提供值。”在这一行中“第76行：cmd.ExecuteOnQuery（）；”好的，我在我的quesry字符串中添加了该代码。新错误“System.Data.OleDb.OLEDBEException:Parameter@Image没有默认值。”@PetersonPilares我确信您添加Image参数失败。我已更新代码以显示图像参数和id参数。再次确认“异常详细信息：System.Data.OleDb.OLEDBEException:parameter@id没有默认值”。我复制粘贴代码并将其放入查询字符串中。嗯…我的网站url没有返回到/上传照片？id=60…只进入/UploadPhoto@PetersonPilares你使用gmail/yahoo聊天吗。。这样做很容易得到帮助。
