changing src of iframe from server side !!!HELP!!!!

Hey all,
I'm writing an application where I'm using an iframe to load up various dynamic information. I have a flash app that I load up in that window, that I pass values to depending on what the user selects from various drop down boxes and such. It would be alot easier to just do a popup, but unfortunately i'm not able to do that given the client.

My problem is that I don't know how (or am able to find anythign on) to change the src of the iframe. Basically I want to change it to customize.swf?var1=" & var1 & "&var2...etc... when the users clicks to view a preview. I've tried having it run as a server control, as well as declaring it and then in the vb codebehind saying ipreview.src=bla bla bla...but it keeps saying that .src isn't "a member of 'System.Web.UI.HtmlControls.HtmlGenericControl'." I'm really running out of time and I'm not able to find anything on how to make this work... please help if you can.

You were right on track with HTMLGenericControl. Just use the AddAttributes method

VB Code:

MyIframe.Attributes.Add("src","somepage.aspx")
