Created IgGrid with 255 Rows and 15 Columns. I have fixed the GridHeader.
But when i move Vertical scroll bar Very slow response from the grid. Grid rows are moving very slowly.
Issue was persists in Internet Explorer.
Kindly advice any solution for this.
Thank you for posting in our forum.
In order to be sure I understand your scenario, some additional information would be much appreciated:
Please note that the grid headers are fixed by default - the “fixedHeaders” default value is true and there is no need to enable it.
If you need any additional assistance, feel free to contact me.
Thank you for the information. I am sorry if I have expressed myself badly - what I meant by “Ignite UI version” was the version of the product – typing “$.ui.igGrid.version” in the browser console would give you the build number.
I tried reproducing this behavior on my side using an MVC sample that has a grid with 255 rows and 15 columns filled with dummy data as well as the initialization options you have provided. The scrolling was smooth and I didn’t experience delay in the response time. For testing purposes I have used MS Internet Explorer 11.112.17132.0 and Ignite UI version 18.1.152.
Maybe there is something in your configuration that I am missing? Please try running the provided attachment on your side and see if this performance problem would appear. Feel free to modify it if necessary and please send it back, or send a small sample project of your own if you have one.
As a general performance improvement advice I would suggest that you either enable the grid virtualization or use remote Paging (if it suits your scenario) – they could decrease the number of elements in the browser DOM and have a positive performance impact.
Feel free to contact me if you have any questions regarding this matter.
