Hi I have a grouping grid which does not seem to be calculating the max horiz scoller value correctly. If I scroll to the right so that al cols have been scrolled, there it still a bitleft in the scroller and clicking it again gives me an exception. Any suggestions, please??? Exception = ''1291'' is not a valid value for ''value''. ''value'' should be between ''minimum'' and ''maximum''.

Hi Jason, that''s tough to give suggestion without a sample. I will need to debug into it... The exception itsself does not ring any bells what might be wrong. Is it possible to create a sample that shows the problem? Thanks, Stefan

Hi Stefan, please find attached my sample applications. Run the application and then narrow the width of the form so that not all of the visible columns are shown. If you scroll to the right using the scroll bar and keep clicking you''ll get the exception Jason Test Grouping Grid1_6922.zip

Hi Jason, I think this was only a problem with the private builds. Jay could see it but it seemed fine on my machine with latest code. Jay will send you dl instructions for latest code and then let me know if you still see it. Stefan
