if I sort a column and then the next, I never can remove the sort again.
Hello bet32978,
Thank you for posting in our community.
A column can be unsorted by pressing SHIFT + click on the header of the igGrid column that you want to unsort. I tested this approach in the Grid > DataTable Binding sample. I sorted "Region" column and afterwards "Postal Code " column. When I press SHIFT and click on the columns headers they get unsorted correctly. Please test this on your side and let me know if you have any additional questions afterwards.
