View 1 RepliesI have an app which hangs in production periodically more frequently on some PC's than others. While trying to resolve this I have started to analyse the application using WIndows native debuggers, such as ntsd,which appear to throw up a large number of clr exceptions (first chance). While alot of these are handled in my code some appear to be related to issues with Windows binding. For example the exception' Cannot bind to the new display member' appear to occur when I assign a BO to the datasource of a bindingSource control while if I directly set the datasource of a UI control, which would have referred to the bindingSource, the message disappears.In all cases I would have the displaymember and valuemember set for my list controls before updating the bindingsource control's datasource.
View 2 RepliesIn silverlight, can you bind to a property that contains parameter? For example, the following doesnt seem to work. Am I missing something or is this not possible?

Just asking for personal preferences, pros,cons on the following situation. I have a class(classA) that has some shared members in it. I have a procedure in a form that needs to execute a function in a separate class(classB). This function requires some of the shared member values from classA. I can either pass these values as parameters from the form to classB, or in classB I can just access them directly by referencing classA. As a general rule I've tended to try to use parameters to pass all the information a function needs but it starts to seem a little unwieldly when passing several parameters to multiple procedures.
