Remove Row with Javascript and Aggregates/Groups not refresh

[Robert Madrian]

Hello,

If I use the following code to remove a row in the grid and the grid has Aggregates/Groups this Aggregates and groups are not refreshed...
(without Aggregates/Groups it works) see attached picture...

 

[Robert Madrian]

here is the code for removing the row:

var grid = $(gridname).data("kendoGrid");
var dataitem = grid.dataItem(grid.select());

// Datensatz entfernen
grid.dataSource.remove(dataitem);
grid.dataSource.sync();

Hello Robert,

I was not able to replicate the problem on my side.

That said, could you please share a sample project that replicates the problem. If this is not doable, you could also prepare and share a Dojo.

I look forward to your reply.

Hi Robert,

Thank you for providing the project and the video. I was able to reproduce the problem.

To overcome this behavior, I would suggest handling the requestEnd of the dataSource and invoking the read method:

• http://docs.telerik.com/kendo-ui/api/javascript/data/datasource#events-requestEnd
• http://docs.telerik.com/kendo-ui/api/javascript/data/datasource#methods-read

For example:

.DataSource(dataSource => dataSource
...
.Events(events => events..RequestEnd("onRequestEnd"))
...
)

<script type="text/javascript">
    function onRequestEnd(e) {
        if (e.type == "destroy") {
            e.sender.read();
        }
    }
</script>
