I'm curious if there are any muti-sort modes?
Our testers were confused by grids where we had enabled multi-sort, they told us the grids weren't sorting. But, the issue was they expected a single column sort and weren't aware they had to unsort the original columns in order to get that.
Other grids I have worked with that support multi-sort required some keymodifier with the click to add a column to the current sort list.
So, perhaps clicking cleared all the other sorts and Shift-Click or Ctrl-Click was used to add an additional column to the sort.
Is there such a mode as this in the kendoUI grid? If not, any one have any ideas how to handle this a bit nicer?
