Hi,
The above setup causes vertical scrolling within the grid to become very slow. The only thing we need to show in our cells is the border, background, and foreground text, therefore we're not really making full use of WPF's content model. Do you know of any ways to improve responsiveness in this sort of scenario?
Many thanks,
James
HI,
I submitted a feature request for your lightweight grid (PI13050006).
I will email you shortly with the details.

Hi Matt,
Thanks for sending over the sample application. I've no doubt that were the sample running on a machine with a more modern spec than the one I'm confined to then the scrolling would be nice and smooth. On my machine,however, it's much too choppy to put into production. I think this is unavoidable when there are so many content controls in view - all needing to be meaured and arranged. You need decent horsepower to compensate.
I wonder, have Infragistics every considered the idea of implementing a lightweight grid for rendering text only, based on DrawingVisuals? I ask because in many cases the content model seems overkill for rendering a grid of text glyphs.
Thanks again for getting back to me.
Best regards,
I am attaching a sample using 12.2.2156.
I was able to grab the scroll thumb and drag it without issue.
Please run the sample on your machine and let me know the performance and what you are expecting.

Thanks for replying. The XAML is as follows (OptionsView is a DataView with ~60 columns):
<igWPF:XamDataGrid DataSource="{Binding OptionsView}" ScrollingMode="Immediate" AutoFit="True"/>
I'm using v.12.2.20122.1000. I'm just about to leave the office, so will respond to any reply on Monday.
HI James,
Can you tell me the version and build of NetAdvantage you are using and attach your xaml .
