Re: Can you set a "required attribute" on control property?

When creating a property for a server control can you set some sort of "required attribute", so that the developer sees the browser message you see when you leave off an attribute on a Microsoft control:

Parser Error
Description: An error occurred during the parsing of a resource required to service this request.
Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: The required attribute 'ContentPlaceHolderID' is not found on 'Content' control.
Source Error:

For right now I am just throwing HttpParseException during the Init, but that does not behave like Microsoft's controls.

Thanks.

It would be helpful if you include some code.

Normally, in a .net application you would provide a RequiredValidator; something like:

<asp:RequiredValidator ID="someId" ControlToValidate="yourcontrolID" Display="Static" InitialValue="" ErrorMessage="Please provide a value." runat="server">

Judging by the error message you are getting indicates that you are adding your control to a placeholder that does not exist.

I hope this helps.
