You cannot do this with a user control (ascx file). As there is no way to access the "inner HTML" code, that the control is wrapped around. In order to do this with a user control, you'll need to define a string property on your control, e.g. Contents which you can then use in the markup:

<cc:MyControl id="MyControl1" runat="server" Contents="Hello World!"></cc:MyControl>

Hi there

You can, but it makes not really sense and the result is far away from good :)
If you try it on a blanc usercontrol, you get this:

--
Parser Error Message: Literal content ('Inner Content') is not allowed within a 'ASP.usercontrols_testusercontrol_ascx'.
--

If you apply the [ParseChildren(false)] attribute on your codebehind class of the usercontrol, it looks like:

UserControl (ascx) content:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TestUserControl.ascx.cs" Inherits="UserControlTest.UserControls.TestUserControl" %>
<p>
    This is a test content.
</p>

Testpage content:
        <pb:TestUserControl ID="ucTest" runat="server">
            Inner Content
        </pb:TestUserControl>


Html output result:
<p>
    This is a test content.
</p>
            Inner Content

 Thanks for both of your replies.

johram, I have tried your method before, but what if I wanted to use more complex content? for example:

<cc:mycontrol>

<asp:textbox />

</cc:mycontrol>

I dont believe its possible to simply put <cc:mycontrol contents="<asp:textbox />" />

If you want to create a custom control containing plaint html or other controls create it as a webcontrol using templates. Here are some articles about it:

I second toas1 suggestion, you'll need to go down the advanced path and implement your own custom control. There are a couple of good articles on the subject if you google - but I must inform you that it will not be as easy as setting up an ascx thingy. You will have to take care of both page rendering code and designer rendering code yourself (if needed).

Actually you can do what you are asking with a <System.Web.UI.UserControl>.

Using the ParseChildren attribute you can specify to allow the literal content and also which property to put it in. The property needs to be declared in the class. I have used code similar to this ...

 

[ParseChildren(true, "InnerContent")]
public partial class MyControl : System.Web.UI.UserControl
{
    public string InnerContent
    {
        get { return MyPlaceHolder.InnerHtml; }
        set { MyPlaceHolder.InnerHtml = value; }
    }

    ...

}

 

In the designer ...

 

<div id="MyPlaceHolder" runat="server"></div>

 I also saw that you wanted to have child controls inside your usercontrol. You have to indicate you want to parse as controls, so in that case use ...
 

[ParseChildren(false, "InnerContent")]
