ejs-grid ERROR TypeError: Cannot read property 'matrix' of undefined

[Don Liang]

I have an Angular drilldown modal with  datagrid <ejs-grid #overviewgrid id="drilldown-grid" [dataSource]="drillDownData" [allowSorting]="true" gridLines="Horizontal" rowHeight="38" height="100%" width="100%">.

using to assign the values.

this.theService.getTheData({

      "AppUserID": 1

    }).subscribe((next) => {

           this.drillDownData = next.detailData;

})

but seems like when the data size over 400, it pop up 

ERROR TypeError: Cannot read property 'matrix' of undefined

    at FocusStrategy.../../node_modules/@syncfusion/ej2-grids/src/grid/services/focus-strategy.js.FocusStrategy.onFocus (focus-strategy.js:56)

    at ZoneDelegate.push.../../node_modules/zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:421)

or if the data size is around 50, initially there is no errors, but after I click the drilldown popup link 3 or 4 times, I see the same error as I mentioned above.

Is there a way to fix this error? Does it matter to the application? Please let me know. If you need more details, please let me know also.

Thanks

Don

Hi Ajith,

My syncfusion version is 18, angular version is 9.1.3.  It's really hard to share the complete code with you. I can share the HTML, the ts, mock data json file. and 3 screen shots  as attached. 

Thanks for your helps

Don
