Very nice article -- but you're always one of the best writers. :) Check out my dynamic button for some more options -- http://www.wilsondotnet.com/Demos/Buttons.aspx.

Peter, you get this error when you visit the page through your browser, or when you are adding it to the VS.NET designer? If it's the former, make sure that each RoundedCorner control on your page has a unique ID.

Peter, found the problem, and will update the article later today. You can fix this yourself, though, if needed. Basically you need to have the RoundedCorners class implement INamingContainer. That is, in RoundedCorners.cs change line 18 so it reads:

public class RoundedCorners : System.Web.UI.WebControls.WebControl, INamingContainer

Primortal, glad you like the control. Adding the support you're after is on deck. Hope to find time to get it done this weekend.

Thanks!

Nice control. However, it would be nice if an aspx file that showed various usage examples was included in the zip file. Not everyone wants to use Visual Studio.

Ability to put a datagrid / whatever inside as primortal suggested would be great.

Great job, Scott.

Several questions and suggestions...

I wish to create your control programmatically and extract the resultant HTML for use within a custom component. How can we obtain the HTML as a string?

How do we set the TitleStyle property via code-behind? It seems to be readonly.

# re: As Promised, the Article on the RoundedCorners Web Control 8/4/2004 2:11 PM Scott Mitchell

Marc, you should be able to simply call the RenderControl() method, and extract out the rendered HTML. I discuss how to do this in an article that looks at emailing the content of a DataGrid:

Scott did an exciting job since I am fasinated with rounded corner style in web page. To make it more useful, I did some <a href=http://site230.webhost4life.com/billxie/demo/TemplateRC.aspx >enhancement</a> to make it a template control. Now text can be any anything you like.
