I've created a new Edit Page for a document library, I've used a Custom List form to generate it and added a 'FileUpload' to it.
I've create a dll that overloads the page, so that on a postback I can get the content of the FileUpload. However, I cannot get a reference to the DVWP on the page. Page.FindControl doesn't work (null), if I use the SPLimitedWebPartManager, then I get the DataForm WebPart but there are no controls in it to reference.
If I use smartpart and make it an ascx, the xsl bombs with an 'input string not in correct format error'.
So in short: When a page is loaded how can I get hold of the a DataViewWebPart, and find it's controls? Can I get a reference to the Page WebPart manager instead and find it? Regards Paul
