Thanks for contacting Syncfusion support.
Query : However, when trying to show/hide columns, I noticed that the grid takes a few seconds to update/re-render on the screen. The tests were done on IE.
We have analyzed your query but we are unable to reproduce the reported issue at our end. If you have tested the component with more number of columns or data, the grid may vary in terms of the performance due to data loading duration. So please find the below sample and video demo for your reference,
Please provide below information of details to look into this issue further,
- Please share your grid configuration/ full code example?
- Please share your Internet Explorer version details?Regards,Thavasianand S.
