Master-Detail Grids - Detail Grid not Refreshing in Expand Mode - Angular 10

[Rajeev]

Hi,

Recently upgraded the angular project from 8 to 10. After the upgrade we noticed in master details grid details grid template which is in expanded mode is not refreshing while we invoke parent grid refresh. It was invoking the detail template ng onint in earlier version of angular. we are forced to collapse and expand to make the refresh happen. Is there any additional property missing in new angular/kendo version.

Angular Version -  "@angular/core": "10.2.0",

Angular Grid Version - "@progress/kendo-angular-grid": "4.8.0",

 

Thanks

Rajeev

Hi Rajeev,

I am not sure what is your exact implementation, but it seems that you need to use the trackBy() method as demonstrated in the following forum thread in order for the Grid to reuse its rows and detail templates by reference and not by index:

I hope this helps.
