Dear Support Team,

I have a grid which is showing a dataset which has thousands of rows data.
When the next datafeed comes in, I'd like to highlight the cell of which the value is updated or changed.
In the menudatabound event, I tried to compare the two datasets (one is the old and one is the new) and try to highlight the change using a line as below:

$("#mygrid tr[data-uid='" + row.uid + "']").find("td").eq(k).css("background", "lightgreen");

It's very slow, it's OK for up to hundreds of rows.
We don't use any paging in the front-end nor in the back-end datafeeding service.
Can there be any workaround?
Can you please advise any alternative?
Is there any faster way to access the background color of the cell and change it?

Thanks & regards
UFIS

Hi,

Basically there is no better way of finding the needed row other than using the model "uid" and in current case I can only suggest to try optimizing the selector for finding the cell at given index. Also you can try optimizing the loop that you are using for comparing the two data sets. For more information about how to optimize the selectors you can check the following thread at StackOverflow:
