Title: Datagrid performance Post by: sectioni on August 10, 2017, 03:31:50 AM Hi,
I have disabled the following in my datagrid: nowrap : false, fit : false, fitColumns : false, autoRowHeight : false My columns all have a width defined, and I am loading 700 rows. Performance analysis shows that rendering is responsible for 5.6 seconds lag. getClientRects => $.fn._outerWidth => getCellWidth => .each => autoSizeColumn is responsible for most of it. What is the reason this function is running? Thank you.

It loads 1000 rows at a time quickly. Title: Re: Datagrid performance Post by: sectioni on August 16, 2017, 07:37:49 AM Hi,
I managed to find the reason! If i set my columns programmatically, and I have a column that's hidden, and it's width is set to 0 or no width parameter at all, then rendering is 3-4 times slower on Chrome, and about 1.5 slower on Firefox You can test it here: https://jsfiddle.net/xwyq3ehd/14/ Run the script, Click Load, Watch the time. Then change the width value on the first column to any number, Run the script, Click Load and watch the time again.
