Allows you to include a sub-control webcontrol between control labels.

I wrote about usercontrol before http://www.cnblogs.com/coolkiss/archive/2010/09/07/1820467.html.

But the manager said that usercontrol is not reusable, so he switched to webcontrol and encountered some problems during the change process.

The main problem is that the control label contains sub-controls or Asp.net page variables.

 

The function I want to implement is to include sub-controls between controls.

<CC: titleex runat = "server">

<Asp: literal id = "litstr" runat = "server"/>

</CC: titleex>

 

At the same time

<CC: titleex runat = "server">

<% = "Hi" %>

</CC: titleex>

 

It can also be used as follows:

<CC: titleex runat = "server">

<% Response. Write ("str"); %>

</CC: titleex>
