I have a range column in infragistics grid. After sorting the values by clicking the header of the column the sorted data looks like below. The resulted sorted data doesn't look fine. Please advice
What's wrong with the data as it is sorted here? The sort order appears correct to me.
They are most likely being sorted as strings. They don't look like numbers to me so to make them sort like numbers, you would have to implement the IComparer interface on a custom class and assign that implementation to the column's SortComparer property.
