C#.Net equivalient to Evaluate

Is there a C# version of Evaluate?
I have multiple controls I'm placing on a form using a query. At post back I need to retrieve the values. Using Request["field" + x] won't work for me in this case.

I'd say that, just as in CF, you don't need evaluate as often as you think.
Here's an example that I think demonstrates what you're thinking: <%@ Page language="c#" %> <% string x="Name"; Response.Write(Request["field" + x]); %> If I call that as filename.aspx?fieldName=bob, the output is bob. Is that the kind of abstraction you're looking for (though I realize you're probably using form fields instead, it shouldn't matter at all.)

I this case I can not use Request - at least easily. The full client side
name gets changed to something like __ctr00content_pnlAdd_txtFieldName (I don't have the code in front me at the moment) because it is embedded within a couple of other page controls. It would be much easier if I could just get to the variable using its server side ID, as I do not want to hard code the full name of the variable in the code.

Oh, I'm sorry. When you said "Using Request["field" + x] won't work for me
in this case," I misunderstood. I thought you were implying you hadn't tried it or that it wasn't working at all. So it sounds like the dilemma is that you want to determine the form fields that MS generates as a result of using Server controls, and then refer to those as passed in. Is that right? In CFML, we'd use form.fieldnames. I don't know if there's an exact equivalent, and I haven't poked around but they have to be there as part of the request somehow. Perhaps there's a method in the httprequest object. Or someone else will have an answer. Good luck.

I am generating the textboxes on the fly by looping thru a query. As I loop
thru the query I give each textbox its own unique ID, "tb_" + ident field from query. In .Net after the PostBack has occurred I can retrieve the value of a form field using its server side name instead of its client side name. In this case the server and client side have very different names. I just cant figure out how to build the server side name on the fly. There is an array of controls that is available, Page.Controls, but it only has one constructer (that I know of) and it takes an int. If I could do Page.Controls["tb_" + ident field].Text, I'd be golden. I'm sure there a simple answer to this - I just can't find it anywhere.
