Treegrid rendered incorrectly in Angular 9

[Damir Gabeljic]

Hi

treegrid component doesn't get rendered correctly when using Angular 9.

I used your example https://ej2.syncfusion.com/angular/demos/#/material/treegrid/checkbox-column and updated project to Angular 9 (no Ivy).

Angular 8: works fine

Angular 9: doesn't work

We have provided the angular 9 compatibility support from v17.4.51 onwards. Please find the below release notes

For your convenience we have prepared a sample in angular 9 , kindly refer it below. 

https://www.syncfusion.com/downloads/support/forum/152143/ze/angular_9_sample-630058408 

We suspect that due to the compilation problem , treegrid rendered incorrectly in angular 9 in stackblitz sample. 

Kindly get back to us, if you need more assistance on this.  

Please revert us, if you need more assistance

Yes, your sample renders correctly, because Ivy is enabled by default.

But if you turn off Ivy (as I stated in first post), it renders incorrectly.

tsconfig.app.json

  "angularCompilerOptions": {

    "enableIvy": false

  }
