I am writing an ASP.NET tool that will allow the client to create their own
online froms. ie the client can add tect boxes, text, drop downs,etc with
absolutely no technical skill what so ever. The form can then be deployed to
their intranet.
The form designer is somewhat WYSIWYG but it contains a heap of 'edit',
'delete' and reordering buttons that are not seen when the form is acutally
being used.
I would love to have a preview image of what the form will actually look
like when it has been rendered in IE and display it in the form designer.
Much like a the print preview in Word.
I figure that my server would need some component that would acutally render
the page in some invisible IE and then take a screen shot of the web page
and then return the image. The designer could then hyperlink to that image
so the use could see a preview.
Another option would be to have an embedded frame but to adjust its 'zoom'
to be very small. Unfortunately frames do not support such a mythical
'zoom' feature.
Does any one have any idea about how I might solve this problem?
The poor mans option is to have a Preview button in the designer that will
lauch a new browser window and display the form but I am trying to steer
away form this.

Dave AHi Dave,
If I understand you right, you want to show a preview of the form to your
user, right? How are you rendering the final HTML? Are you using ASP.NET
server controls? Or are you just rendering straight HTML? If you are just
rendering straight HTML, you can update a <div> tag or <asp:Label> control
with your final HTML. You can do this on the server-side by simply
instantiating a HtmlGenericControl for your div tag and updating its
InnerHtml property with your final HTML...i.e. something like this:
<div ID="PreviewPanel" runat="server">
</div>
And in your server code:
// optional, depending on if you are using ASP.NET 2.0 or not
public HtmlGenericControl PreviewPanel;
[C#]
string finalHtml = "..."; // set this to your application generates
PreviewPanel.InnerHtml = finalHtml;
Voila, you are now rendering the HTML on the page. Just make sure to do this
upon every refresh, i.e. after every time your client updates something on
the page.
If you want to do something more complicated, i.e. render the ASP.NET server
controls, let me know.

Sorry - I should have been more clear. I want a thumbnail representation of
what the page will actually look like.
