Hi Zaw,

Thank you very much for the screenshot provided. 

Based on the information in the question, I managed to reproduce the issue with the unexpected scrolling when auto-resizing a column of the Grid. Having consulted the matter with our team, it turned out that the current behavior is indeed a bug on our side. 

For this reason, I logged an issue in our public GitHub repository and what I would suggest would be to subscribe to the issue in order to track the resolution process:

https://github.com/telerik/kendo-angular/issues/4129

In the meantime, what I could suggest as a workaround would be for the developer to set the virtualColumns property of the Grid to true and use the built-in scrollTo method to ensure that the component's scroll does not move unexpectedly. To better illustrate the suggested approach, I am sending you a StackBlitz demo that implements it:

Please, keep in mind that the demo aims to point the developer in the right direction but might need additional modifications to fully fit the case-specific requirements.

As a token of gratitude for pointing out this issue to us, I updated your Telerik Points.

In the lines of words I would like to apologize for any inconveniences that this unexpected behavior might have caused.

Please, do not hesitate to reach out if any further details are needed.

Regards,
Georgi
