Is it possible : rendering server tags at runtime in asp.net?

Question

Is it possible that I reserve a asp.net code in db and load it at runtime. the asp.net code contains server side tags like Text='<%# Eval("Description") %>'

Answer 1

You can write to an aspx, plugging in what you want and then build the page using:

BuildManager.CreateInstanceFromVirtualPath("~/MyPage.aspx",typeof(Page));

You'd need to wrap that when getting your HttpHandler:

var p = BuildManager.CreateInstanceFromVirtualPath("~/MyPage.aspx",typeof(Page));
HttpContext.Current.Handler =p;

(BuildManager is in System.Web.Compilation)

That's just an idea....but I wouldn't do this, as you're going to pay the compilation cost every time (which is really high compared to pretty much any other operation), and you'd need to bump your application files writes before restart (default 15).

Short answer: Yes you can do this, but I wouldn't. There's most likely a much better way to achieve your goal, maybe if you gave a bit more background, we can provide a much better solution.
