I have a grid where I want to be able to hide some columns on first page load, a default view. I have seen all the examples on the samples site and they are all in jquery. We are using AngularJS in TypeScript. In the attached zip file you will see a simplified version of the grid where I'm just attempting to follow the examples on your site and I keep getting the 'hideColumns()' is not a function.
Thanks for any input on this issue!
