Is it possible to hide the default expansion indicator on Treegrid rows that have no children?

Martin

I've tried to handle this in the queryCellInfo and it seems to work for the first page when paging is on but not on subsequent pages. Looks to me like the queryCellInfo event is not fired when going to next page.

Here's my code - I think it's too wide a scope on the css selector but I can get more specific once the event fires when going page to page:

function queryCellInfo(args) {
    if (args.data.hasChildRecords === false) {
        $(".e-treegridexpand").css({ "display": "none" });
        $(".e-treegridcollapse").css({ "display": "none" });
    }
}

Hi Martin, 
Query 1: Is it possible to hide the default expansion indicator on Treegrid rows that have no children? 
Solution:  Only the Parent records having expander/collapse icon in Treegrid. These icons were absent in the tasks with no children.so could you please share more details related to this query with us and it will be very helpful for us to understand your requirement clearly and update the response?  
   
Query 2: I've tried to handle this in the queryCellInfo and it seems to work for the first page when paging is on but not on subsequent pages. Looks to me like the queryCellInfo event is not fired when going to next page. 
Solution: We were able to reproduce the issue in queryCellInfo trigger while selecting the subsequent pages in Paging and we have confirmed this as bug and logged a report on this. Also we have created a support incident under your account to track the status of this issue.

With regards to query 1, this JSFiddle shows the issue. For the first row "No Children", the subtasks array is empty but the row is rendered with an expansion indicator.
