Native Grid Row Select, why is there a lag between selection?

[Joe Sugden]

Even in this example provided in the documentation: https://98razv.run.stackblitz.io/ from https://www.telerik.com/kendo-vue-ui/components/grid-native/selection/

When there's more than a few 100 rows of data, there is a significant lag when selecting a row from the grid. Can someone guide me into understanding why this is happening and how could it be avoided or if there's a better way of doing selection?

Thanks.

Hello Joe,

I created an example that works a bit faster. You can check it out here: https://codesandbox.io/s/kendo-grid-native-selection-ou6cp. 

The reason for the lag is the array traverse mechanism. However, without it there will be no selection state for the items.

If you think that an internal selection state would be more convenient for you, please share that in our feedback portal: https://feedback.telerik.com/kendo-vue-ui.
