Custom Control won't appear in design mode?

[Dave]

Hi,

I created a custom control, regisitered it at the top of the page, and it works fine. However, it doesn't appear on the page during design mode as I've seen other controls or event ASP.NET controls (i.e PlaceHolder) as listed below

DESIGN MODE:

[ControlClass "ControlClass ID"]
or
[PlaceHolder "plcMyPlaceHolder"]
....
What do custom controls need to implement to show up on the design mode page like this?

Thanks, Dave.

Expose some property and assign some value to it. Custom control will show
up in design mode.

Thanks for the reply. But I think I'm already doing that. I'm creating a custom tabstrip control and create it on the page as:

<CustomTabStripControl:TABSTRIP id="TabStrip1" runat="server" DefaultTabId="TabOne">
<CustomTabStripControl:TAB id="TabOne" runat="server" />
<CustomTabStripControl:TAB id="TabTwo" runat="server" />
etc.

DefaultTabId is a public property that I define in TABSTRIP class as:

public string DefaultTabId
{
get
{
return _DefaultTabId;
}
set
{
_DefaultTabId = value;
}
}

Expose some property and assign some value to it. Custom control will show
up in design mode.

You need to add a class derived from ControlDesigner to your control,
and add this class as a DesignerAttribute to your control class.

The class should implement a GetDesignTimeHtml() method,
which allows you to produce whatever HTML you want to appear
in the designer.
