LOOP THROUGH A DATASET

I had a reason to loop through a dataset today and I was just wondering someone could be in need of this. I believe it is straight forward.
I am assuming here that you have already created your dataset (ds).

foreach (DataRow dr in ds.Tables[0].Rows)
{
//Do whatever you like here with the rows returned
Response.write(dr["columname"].ToString());
}

PublishingAssociatedContentType

The Content Type to be associated with a page layout is indicated by the 'PublishingAssociatedContentType'. In the actual sense it means a binding setting between the Page Layout and the content type. If you fail to provide one, the SharePoint framework will make use of the Page Content type. The format of the binding is: ';# e.g. ';#ContentPage;#0x010100C568DB52D9D0A14D9B2FDCC96666E9F2007948130EC3DB064584E219954237AF3900470b13dd348649d08f9e5151501df9a4000dbd46dad8d045f98c83ad983b66d3f2;#'. where Content Type name: ContentPage Content Type ID: 0x010100C568DB52D9D0A14D9B2FDCC96666E9F2007948130EC3DB064584E219954237AF3900470b13dd348649d08f9e5151501df9a4000dbd46dad8d045f98c83ad983b66d3f2 respectively.
