[Solved] Performance Issues in IE10

[Bradley]

We are experience significant performance issues when loading and editing our Kendo UI grid when the grid has approximately 100 rows and 40 columns.

We so not see this problem when the grid only loads a few rows with 10 columns.

The loading, editing, add new rows, saving, and refreshing are all unacceptably slow in IE 10, in compatibility mode, while Firefox (24.7.0) does not have these issues.

Do you have any ideas as to how we can deal with this issue or why we are getting it?

Thanks,

Bradley

Also, we are using AngularJS with Kendo UI

Also, please let us know of any known performance issues with IE10 for the Kendo UI grid,
1 specifics of performance issues,
2 causes if known,
3 workarounds if known,
4 and if replacing angular binding of grid with Kendo binding will improve performance?

This is a critical issue for us if we are to continue to use Kendo, since many of our users use IE 10.

Thanks,

Bradley

Hi Bradley,

The performance delay that you observe in IE10 is somewhat expected. In general IE10 has some performance issues when it comes to JavaScript rendering compared to other browsers, and this is further delayed by the compatibility mode. Further performance delay comes from the AngularJS bindings that require significant JavaScript performance. 

At the moment there is nothing that I can offer you in order to speed up your application, different than removing the AngularJS bindings from the application, which should improve the performance.

Kiril,

Can you give example of code that uses Kendo binding of grid data used in or with an angular controller?

That is, I see examples of Kendo binding of data to grid, but not when used in conjunction with angular. And we are still using an angular controller for the parent div of the div that holds the grid, even though we now want to replace kendo angular directive for binding grid with jQuery code to bind data source to the grid.
Thanks,
Bradley

Also, I would like to know if other users have reported grid performance issues in IE10, if these issues were associated with using kendo-angular bindings, and how the issues were resolved.

Thanks.

Hello Bradley,

In general using AngularJS along with the standard jQuery Kendo UI binding is not recommended. The problem comes from the fact that you will need to update the Angular models individually, which will remove all the advantages of the AngularJS integration.

As for the performance issues - did you check the performance of the Kendo UI Grid without AngularJS? Is the performance improved?
