sort grouped headers by sum value

Hi all,

I would like to request a feature by enabling sorting of grouped headers only by the sum of values in a specified column.

Thank you.

Hello,

Here you will find a small Dojo sample that demonstrates how grouping is first cleared in a Kendo Grid and then reset:

https://dojo.telerik.com/EZoYuRIS

Attached you will find a short video demonstrating how the previous state of grouping is properly returned to the Grid.

Do you observe different behavior at your end? If yes, could you, please, prepare and send me a Dojo sample demonstrating the issue in question?

Looking forward to hearing from you.

Hi Veselin,

 

I am not able to trigger the columns.groupable.sort.compare function programmatically. I have tried resetting the group by calling dataSource.group([]) then regroup using dataSource.group(groups) where groups =  dataSource.group(); before resetting the group to an empty array. Any advice on a workaround or solution to the problem? Thank you.

Hi,

The requested could be achieved by implementing a custom group.compare function. Here is the API reference and a short example demonstrating how to implement the desired:
