Resolution of any property / attribute on server / usercontrol

Question

I noticed that on most, if not all, standard web controls in the System.Web.UI.WebControls namespace, you can add any properties you want to them without page crashes.

Take an asp: Button control for an example.

This code is absolutely correct:

<form runat="server">
    <asp:Button runat="server" Text="Test button" crapAttribute="crapValue" />
</form>

Now I have a custom server control that crashes if I add arbitrary attributes to it. It accepts only attributes that have the corresponding public property.

The error I get looks something like this: "The control does not have a public property named" crapAttribute "."

I would like my user controls to be able to accept any attributes without crashing. What do I need to do for this?

I looked at the standard controls in Reflector, and they have all kinds of attributes and more, but I did not see anything that immediately caught my eye.

My user controls inherit from WebControl for what it costs.

Answer 1

You do not need to do anything, in particular, to add attribute attributes. Things originating from WebControl typically scoop up these attributes and upload them to the collection of attributes.
