Hi,

I am trying to populate a grid from 2 BO's by creating custom fields in the 'master' BO. My code for the custom field properties is :



My form has the following event enabled:



When I hit the assignment to computerName I get the exception

"Column 'computerName' does not belong to table HLSUserNames."

Can anyone please advise, many thanks

Ian,

First I would reinforce Edhy's suggestion that unless you need in-place editing, a ListView is much easier to user, much lighter weight. The SF ListView also has all the goodness Edhy mentioned related to easily hooking the ListView up to ChildFormDialogs etc.

However, to address your problem, the most common cause for this is that the column doesn't have the correct value in it (i.e. it can't be cast to a boolean). I'd set a break on the line that loads the BO and then step through it, looking at the data table.  Since this works when you load it, you must be doing something a bit differently when you refresh grid.  You might also set a break in the get of the loggedIn property and see what the data table looks like (get_loggedIn is the method generated by the compiler for the get of a property).
