Ultragrid, BeginUpdate() and EndUpdate() on Windows XP with a Classic Theme
posted

Hello,

I noticed something peculiar using an Ultragrid, UltraDatasource, LoadStyle.LoadOnDemand, BeginUpdate() and EndUpdate(). Under Windows 7 x86, 64, Windows 8 and Windows XP (configured with a Windows XP theme) all works smoothly.

However, under Windows 2008 (non aero theme) or Windows XP with a Classic Theme, the background flashes to black for a second using BeginUpdate() and EndUpdate(). When I leave using the two methods out of my code, the background doesn't flash and forth to black and then white. I've tested with Infragistics 2011.2 and 2012.1, both have the same behavior.

What could be the issue here?

regards,

Roel van Bueren

    Hello Roel van Bueren,

    I tried this scenario with Windows XP 32bit, Classic Themed and it seems to work fine. I do not know what you are doing in the begin-end section, so please take a look at my sample, see if it works fine and if so, please modify it, if you can, so it can reproduce the undesired behavior. I will be waiting for your feedback.

    Please feel free to let me know if a question about our toolset comes up on your mind.
