Groupby and sorting issue

I’m do groupBy and I’ve gotten it to work correctly. But then I want the groups in a certain order. I do a sort and it puts them in the right order on Firefox but in IE there wrong. Anyone know why?

I searched and found other people with this issue but I donno how to get around it.

Unfortunately issue can’t be reconstructed locally. Please check example here dhtmlx.com/docs/products/dht … group.html
If issue still occurs for you - please provide any kind of sample or demo link where it can be reconstructed.

I’m not sure but it may have to do with sorting and grouping by hidden columns

I solved my issue. Instead of using the hideColumn method on grid I was setting the columns width to 0 which does the job but messed up the grouping and sorting on ie.

Im now using hideColumn and it works
