XML control not maintaining contents after postback, even with EnableViewState=true

[Justin Crossley]

I have a webform that lists search results using an XML control

The search results are contained in a string called strResults and are transformed using an xsl file into formatted results.

The c# code is as follows:

XslTransform trans2 = new XslTransform();
trans2.Load(Server.MapPath("HitList.xsl"));
xmlSearchResults.DocumentContent = strResults;
xmlSearchResults.Transform = trans2;

This works fine, but I want to be able to do a postback whilst maintaining the search results using viewstate.

If I enable viewstate the xml control is empty after the postback.

Other controls on the form successfuly return their viewstate so everything else appears to be working.

Any ideas anybody?

Thanks
