模板化控件-开头和结尾标签之间不允许包含内容 [英] Templated Control - content is not allowed between the opening and closing tags

问题描述

我正在尝试运行MSDN提供的模板化用户控件示例。代码如下：

I'm trying to run the templated user control example provided by MSDN. Code is as follows:

因此，根据MSDN，这应该实现如下：

So according to MSDN this should implement as follows:

<%@ Register Assembly="MyAssembly" Namespace="MyAssembly.Controls" TagPrefix="abs" %>
<abs:TemplatedFirstControl id = "First"  runat=server
                           Text= "The time on the server is "  >
      <FirstTemplate>
          <h3><font face="Verdana" color = "red">
                 <%# Container.Text %> <%# Container.DateTime %>
              </font>
          </h3>
      </FirstTemplate>      
    </abs:TemplatedFirstControl>

Designer抱怨 TemplatedFirstControl的开始和结束标记之间不允许包含内容，并且不支持 FirstTemplate 。那还有什么呢？我逐字复制了MSDN的代码

Designer complains that content is not allowed between the opening and closing tags of TemplatedFirstControl and that FirstTemplate is not supported. So what's missing? I duplicated MSDN's code verbatim

推荐答案

对于有相同问题的任何人，我发现在FirstTemplate属性中添加以下属性可以解决以下问题：我：

For anyone who has the same problem, I found that adding the following attributes to the FirstTemplate property solved the issue for me:

[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
[PersistenceMode(PersistenceMode.InnerProperty)]
public ITemplate FirstTemplate 
{
    get
    {
        return firstTemplate;
    }
    set
    {
        firstTemplate = value;
    }
}
