What is the limit on number of colums for Grid Control in VS 2003?
Thanks

Hi Peter,
Welcome to MSDN Newsgroup!
Currently there is no document to show this problem. However, as far as I
known, since GridControl has a property "DataGrid.Visib leColumnCount ,
which returns the number of visible columns, the number of columns in
GridControl shouldn't exceed 4G. But it also depends on your memory and
system's resource on your machine.
I hope the above information is helpful for you. If you have any questions
or concerns, please feel free to let me know. I am looking forward to
hearing from you. Thanks!

Thank you for the Info
I am working on a app that will have upto 7000 columns, which are data
points on the graph. I am not sure how exactly I am going to do that. I
don't know what the performance will be with about 2000 rows and 7000
columns. Maybe I should create something like virtual window for this data
and display the grid containing only the current view. This seems to be a
lot of work, so if the Grid can handle that much data I will just load the
gird.
Hi Peter,
Thanks for quick response!
From my experience, it's not reasonable to use GridControl with 2000 rows
and 7000 columns.
I think you may be able to post here to let us know why you need it to see
whether we have some workaround for it. Thanks for your understanding!

I have a application that gathers data from a machine, this machine might
have upto 7000 different variables and I take a sample of the run which
might have upto 2000 reads, which I would like to graph and also allow the
user to view any part of the Raw data in the grid.

Hi Peter,
In this scenario, you could try to load all data at first. However, if the
performance is not satisfied after testing, I suggest you could firstly
make user choose a region ,which he want to view and then load this
region's relevant data instead of loading all data into GridControl. I
think it should improve the performance.

I'll have to load data and see if the performance is satisfactory, if not
than I might have to create some thing like a virtual grid, where the
program would pre-fetch data say twice as big as the Grid Control and than
do the subsequent fetching in the background.
Thanks for your help
Hi Peter,
Thanks for your feedback!
I think it's better for you to test the performance at first. If the
testing result is not satisfactory, please feel free to let me know. I will
be happy to be of further assistance. Thanks again!
