Gridview中的Fileupload.HasFile始终返回false [英] Fileupload.HasFile in Gridview always returns false

问题描述

你好专家，



FileUpload.HasFile总是在GridView中返回false。我在页面加载中添加了以下内容

Hello experts,

FileUpload.HasFile always return false in GridView. I added below in Page Load

Me.Page.Form.Enctype = "multipart/form-data"

我也在更新面板中添加了

Also I added in update panel

<Triggers>
<asp:PostBackTrigger ControlID="btnSubmit" />
</Triggers>

对我来说没什么用。我错过了一些愚蠢的东西吗？

顺便说一句，我的网格是动态生成的。我在页脚中有一个按钮，表示添加新的空行，并添加在空行中输入的文本。

Nothing works for me. Am I Missing something silly?
By the way my grid is generated dynamically. I have a button in footer which says add new empty row and also adds the text entered in empty row.

推荐答案

嗨通过更改Post back触发器中的ControlID解决了这个问题。我将其更改为GridViewID，其中存在FileUpload。如上所述，我的fileupload是Gridview中的一列

Hi Solved this by changing the ControlID in Post back trigger. I changed it to GridViewID where my FileUpload is present. As said my fileupload is a column present in Gridview

<Triggers>
<asp:PostBackTrigger ControlID="gdvItems" />
</Triggers>
