does this work for you?



I tried to get around it but I still need to be bale to capture the value of the column.



This wont go away for me and I have tried many many things.



I have the code copied directly from the help files. It also crapped out on me in a test winform.

Keith,

I have just scanned through this post and I don't think this has anything at all to do with a ListView (or the web for that matter).  Either the business object in e.BusinessObject is not the movesBO or there is more than one visible assembly of the BO library (i.e. registered in the GAC or something).

First, if you place a break point on the line that fail (from your screen shot), before you step through that line, place the e.BusinessObject in the watch...what is the type?  Does it appear to be correct?

That is the first thing I would look at.

I think your onto something.... here is my watch.



movesBO is the Business Object class

movesBO1 is the instance of movesBO declared in ApplicationBasePage for the site to use



I hope this helps........



I thought I had it and tried to DIM loBO as movesBO1, but it didn't like that either.



Thanks for looking.......

Related question.....



Is there a way to do grouping within the ListView in the webforms version of the control?

Well, it is hard for me to tell via the image.  The watch window appears to be OK.  I know that the type looks different, but technically they should both be BusinessLayer classes.  If you try to CType the e.BusinessObject in the watch window, does it give you any more information?  Also, when it throws up in on the CType line, open up the details and look at all of the inner exceptions to see if there is something else in the formula.

Not at the moment...other than...a second list view

I see this is the exception detail on the CTYPE of the BO exception, mean anything to you?



In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user.

I was able to get this working by not casting the e.Businessobject to my BO at all and using:



e.Values(3).DisplayValue = e.BusinessObject.CurrentRow.Item(0) to populate the row.
