WinForms ColorGrid Display Corruption
Posted: Thu Aug 13, 2009 8:27 pm
The WinForms ColorGrid seems to have the same issue that I reported for the WPF version (issue # TW16014129). Just bring up the samples browser for v4.0.2009.28597 (evaluation build) and try scrolling the ColorGrid bitmap demo in all directions (specifically, drag the chart up so that you can see negative numbers on the Y axis).
See: "Welcome !\Chart styles\Statistical\Color Grid\ColorGrid Bitmap"
The image appears to be offset by different amounts as you scroll. As you fix this, you might want to actually add a feature to allow a user to define a fixed offset (x & y, each positive or negative) so that multiple ColorGrid series could be plotted in different areas of the chart (however, the offset shouldn't change automatically when scrolling and the display should not get messed up).
Thanks,
Walt
