[英]How to read content between tags of asp.net server control
I'm writing an asp.net server side control which has a few short parameters passed into it, but also the need to allow a large piece of custom HTML code to be supplied. 我正在编写一个asp.net服务器端控件,它有一些简短的参数传递给它,但也需要允许提供大量的自定义HTML代码。
The easiest way of doing so I thought was to allow to be specified between the tags of the server control, like so: 最简单的方法我想是允许在服务器控件的标签之间指定,如下所示:
<MyControl:Example Runat="server" Id="myControl" Message="This is a message">
<p>This is a long piece of HTML a few dozen lines long...</p>
</MyControl>
How can I access the text between the tags from inside my custom server control? 如何从自定义服务器控件内部访问标签之间的文本?
You need to create a templated control: 您需要创建模板化控件:
<MyControl:Example Runat="server" Id="myControl" Message="This is a message">
<HtmlContent><p>This is a long piece of HTML a few dozen lines long...</p></HtmlContent>
</MyControl>
Where HtmlContent
is your template. HtmlContent
是你的模板。 Generally when I need templates, I simply use PlaceHolder instead. 通常,当我需要模板时,我只需使用PlaceHolder。
public class MyControl : CompositeControl
{
[TemplateContainer(typeof(PlaceHolder))]
[PersistenceMode(PersistenceMode.InnerProperty)]
public PlaceHolder HtmlContent { get; set; }
... render stuff
}
