The silverlight grid we are replacing allowed multi sort, but required control clicking the column header to enable it. I prefer this method over the way it works by default in kendo using sortable: { mode: "multiple", allowUnsort: true } where if you are sorted by ColA and you want to be sorted by ColC user has to first click ColA to unsort then ColC to sort.
I would prefer it to work as follows:
a) if you just click without holding control, the sort is always reset to just the column clicked on - with the caveat that i guess if the column clicked on is already the sort column it toggles thru its states of asc/desc/unsorted like it presently works.
b) if the user is holding the Ctrl key when they click on a column, then the column is appended to the current sort column list if any with the caveat that if it is already in that list, the direction toggles.
Would it be possible to override some things to get this behavior?
