hi, when I try to simulate a Quote screen which getting price in realtime to paint to GGC. it works oK. Onlything, the cell update is very quick , near flash/flip , user hardly to see what the price it is. Any possible way to slowing down a bit or gracefully update the GGC cell ? How ?

even worst, when I sort such high-frequently update column (price) as above, the rows jump up and down, user is hardly to know which row is which. any solution for this by GGC ?

one more questions, say , price = 2.39847 , if new price in 2.39849 , instead of repaint/flash the whole cell, just paint the different digits (in this case, just 9 - which is the last digit) ? thx.

Hi David,

Thank you for using Syncfusion products.

GridGroupingControl has an extremely high performance standard. It can handle very high frequency updates and refresh scenarios. By simply setting few properties, you can have the grid, work with large amounts of data without a performance hit.

You could refer the following page from our online documentation for details:

http://help.syncfusion.com/ug_74/gridwin/Performance1.html

Also you could refer the samples under the following category :

{Install drive}:\Documents and Settings\{username}\My Documents\syncfusion\essentialstudio\7.4.0.20\Windows\Grid.Grouping.Windows\Samples\2.0\Performance\Engine Optimization Demo\cs
Please try this and let me know if this helps.

Regards,
Jisha
