I am currently having issues with the show/hideColumns -- more-so the show feature. I'm referencing the show/hide example found on the documentation page. I have AngularCompileRows turned on and about 90% of my columns (28 columns in total with 8 rows) have custom cellRenderers. I am able to hide the columns with no problems and I can render a portion of the columns (18) with little to no wait time. However, when I hide all the columns and then try to show all 28 columns, it can take quite a while to show up or I get the \"this script is taking too long\" error. Any ideas on how I can speed up this process? I know using AngularCompileRows can slow things down a bit but I didnt expect to get the \"this script is taking too long\" error with just eight rows. BTW, I've removed all cell renderers and tried to show the columns. Same outcome minus the \"this script is taking too long\" error. \r\n\r\nOther than this, I love the library and its ease of use. Great work!

Thanks for your compliments. 😊\r\n\r\nAs this is a question, it should be on the forum, issues are for items that need fixing in the grid. So will close.\r\n\r\nThis sounds like a gerenal 'grid taking to long' question. Usually this is due to grid height not set and the grid is trying to render far more rows than are visible in your browser. This can happen if no height is set on the grid. Please can you verify this? Make sure height is set on the grids div. If using % height, please test with pixels as % can fail based on your parents CSS layout.\r\n\r\nPS if you can move to the forum please. You will prob get help there from others as that's where the community hangs out. I am travelling right now so don't get online often."}}
