Grid 100+ columns and from-markup
I know this has been raised loads of times and i still havent seen a solution. Sorry if one has been found but I wasnt able to find it in the forums.
I have a grid that i convert from HTML to an ext grid. This can have as many columns as required, but performance degrades substantially with the number of columns getting greater than 40. In circumstances where we have 100 columns it takes 30 seconds or so to render the grid - we get this delay again then when the page is resized. Is there anything I can do to remove this issue - I would still like movable columns and resizable - locked/sortable columns isnt really required.
We also have a row size setting so you could end up with 100+ columns and a row size of 250.
Thanks in advance
