Re: <% =expression%> not evaluated in custom control attributes

<%# %> expressions require databinding and can only be used inside of templates or inside of a full attribute value of a control. But the databinding is required as these expressions generate databinding event code.

<%= %> doesn't work inside of server control attributes as you found out because the server control parsing will interpret the expression as a string. Outside of quotes the the quotes but inside of the server expression they are not allowed at all.

As Axel points out the better way to do this is to use codebehind to set the value and while I don't agree about the 'obsolete' comment he makes, in this case that may be the only way that you can get this to work...

The control in question is not data bound.

Is this possible? Is it perhaps possible with a different syntactical
construction; e.g. perhaps with <%# %>?

I noticed that I can use <%#S()%>, but only if I call DataBind() on
the control. As this is a custom control that I don't want to have to
explicitly DataBind(), I am currently doing a 'self-bind' by calling
DataBind() in the control's OnInit(). Is this an acceptable way of
doing things?

Thanks.
