Hi John,
Thanks for using Syncfusion products.
This sample explan the blink functionality in GridDataControl using conditional formatting. Please download the sample from below link.
http://www.syncfusion.com/uploads/redirect.aspx?file=Forum92232_4e713f35.zip&team=developmentWe add two properties OldChange, Flag for maintain old data and weather data gets incresed or decreased. We set the values of those properties while seting the value to Property which we need to blink [Change ]. And In conditional formatting display the cell as green when Flag is true [latest value is greater then old value] otherwise red [latest value is lesser then old value].
We can use the similar technique for DataTable source. We can maintain the property and update the values using ListChanged event and the conditional formating display the style based on the existing condition [Green for Increase and Red for Decrease].
Please let us know if you have any questions.
With Regards,
Dhinesh Pandiyan
