如果webform引用masterpagefile，则Edititemtemplate数据显示为空白 [英] Edititemtemplate data appears blank if webform references a masterpagefile

问题描述

我有一个DetailsView和一个SqlDataSource到SQL Server。如果我有

I have a DetailsView and a SqlDataSource to SQL Server. If I have

MasterPageFile="~/Site.Master"

;然后在编辑模式下，文本框（在EditItemTemplate中）都显示为空白，但您可以单击文本框并退格并删除每个字母。所以奇怪的是文字是白色的白色。当页面引用主页面时，该页面还具有< asp：content>标签代替html，head，body和form标签。



但是，如果我顶部没有MasterPageFile引用，那么DetailsView运行完美，显示应该在编辑模式下的数据。在这种情况下，我使用html，head，body和form标签。



我想使用MasterPageFile引用，所以我可以使用默认的Navbar。



问题： 有没有办法让MasterPageFile引用不破坏EditItemTemplate功能？



我尝试过：



EditItemTemplate出现空白line：

<％@ Page Title =AboutLanguage =C＃MasterPageFile =〜/ Site.MasterAutoEventWireup =trueCodeBehind =MyInfo1.aspx。 csInherits =UserInfo.MyInfo1％>



EditItemTemplate可正常使用此行：

<％@ Page Language =C＃AutoEventWireup =trueCodeBehind =MyInfo2.aspx.csInherits =UserInfo.MyInfo2％>

at the top of the aspx page; then when in Edit mode, the textboxes (in EditItemTemplate) all appear as blank, although you can click into a textbox and backspace and remove each letter. So it's strangely like the text is white against white. As the page references a Master page, the page also has <asp:content> tags instead of html, head, body, and form tags.

However, if I do not have the MasterPageFile reference at the top, then the DetailsView operates perfectly, displaying the data while in edit mode as it should. In this case, I use html, head, body, and form tags.

I would like to use the MasterPageFile reference so I can make use of the default Navbar.

Question: Is there a way to get the MasterPageFile reference to not break the EditItemTemplate functionality?

What I have tried:

EditItemTemplate appears Blank with this line:
<%@ Page Title="About" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="MyInfo1.aspx.cs" Inherits="UserInfo.MyInfo1" %>

EditItemTemplate works correctly with this line:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="MyInfo2.aspx.cs" Inherits="UserInfo.MyInfo2" %>

推荐答案

剪下你的母版页直到它工作;或者，做一个额外的并从头开始直到你失败，一次从老大师那里添加一块大块。



假设你有一个大师在某些时候起作用的页面。

Cut your master page down until it works; or, make an "extra" and start from scratch until you fail, adding chunks from the "old" master a chunk at a time.

Assuming you had a master page that worked at some point.
