Okay . . i am continuing to have this issue and its becoming a serious issue for my application
in both cases i am setting the same value into multiple cell, case 1 via the Clipboard paste event and case two during the CurrentCellKeydown event.
I have reported this before and i can reproduce this in the example file from:
http://www.syncfusion.com/Support/user/uploads/VirtualGrid_49952bec.zip
I have taken the sample and added my code to show you how i am doing the Control+Enter (attached file). It seems the control+enter case is actually a more effective way to reproduce the error.
I you create 10 rows and highlight all rows in 1 column and enter a value and click Control+Enter, all the data updates almost immediately (just like excel) but if you try to move to the next cell via the arrows keys, it takes sometimes up to 4-5 seconds before it moves. It stays on the currrent set of highlighted rows. I keep clicking on the Right Arrow key and sometimes i can click 10 times before it actually moves to the right.
Try to do this in Excel and its instantaneous.
Any suggestions would be greatly appreciated.
thks,
ak
