Ok--found something else not working as stated:

TIO 1504, page 402

I cut (per step 8) the difficult from chapter 1 and put to chapter 2:
I refresh schemas and even recreate the controls..and don't get figure 15-2...the "difficulty" column stays...read on. (after playing with this some--it appears that if you don't have the property in the first child (but in a later child) it messes up.


<book ISBN="98-765142-654" Title="Italian-Thai Fusion cooking" Price="29.65">

In the Databound control, however, it has a "difficulty" column. Next to Pasta vs Noodles it says "Databound" and then next to Tomatoes and Mangos it says "easy"..however, when I build the page I get:

Server Error in '/BegAspNet2Db' Application.
--------------------------------------------------------------------------------

A field or property with the name 'difficulty' was not found on the selected data source.

rsearing:
Ccould be a problem in the XML file. Please post the XML file you used after the cut & paste of "difficulty..."

John,

I think I figured this out. The XML file portion was cut and pasted below..but I can paste the entire file later.

It appears that if you have an attribute (or property--not sure exactly what the term is--basically the 'difficulty' property) that is not stated in the first level, then you get the error. I validated this by removing the "name" property in chapters from all but the second. I got the same error.

The book states that if you have the "difficulty" property on the tomatos book (as below) that the field just won't be shown--not true. In the IDE it shows the difficulty column--shows "easy" next to chapter two and "Databound" next to chapter one..then, when you try to compile, you get an error--it doesn't simply skip the property as alluded to.

Kind Regards,
Rob
