C# - How To Dynamically Render Controls From String

Let's say I have a string that I retrieve from a DB like: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et {{Hyperlink|navigateurl='/foo.aspx'}} dolore magna aliquyam."

This string may now get assigned to the Text-property of a label. What I want is to parse {{Hyperlink|navigateurl='/foo.aspx'}} and replace it with

<asp:HyperLink ID="IDLink" runat="server" Text="foo" NavigateUrl="/foo.aspx"/>

and assign the whole text including the HyperLink-Control to the Label.

Is that even possible? I think I could use reflection to create the control and set the properties. (the HyperLink-Control was just an example) But can I manage to insert the asp.net control back into the string to ensure the hyperlinks rendering as server contorl?

I hope you understand what I want. If not, feel free to post comments.

Edit1:

what do you mean by "assign the whole text including the HyperLink-Control to the Label."? can you xplain a bit, the reason for doing so ?

I think it won't work to assign the control into the string, because a asp.net control cannot be fit into a string.

After some thinking I found a way to achieve my goal. That would be to create a placeholder (I name it A). Therein some Literal control will be added. In addition I would create a placeholder (I name it B), add my Hyperlink into B, and add A into B. But I think is way to overkill.

The reason why I started thinking about this, was to gain access to Server.MapPath without replacing occurences in the string. I want to be able to use relative paths in my CMS, that get rendered like the NavigateUrl property from a hyperlink. Nevertheless I think my question with the dynamically creation is worth thinking about
