I have one column in my kendo grid.
columns.Bound(c => c.PhoneNumber).Filterable(ftb => ftb.Cell(cell => cell.Operator("contains")));
I use the build-in filter for this column. However, my data of "PhoneNumber" is a STRING in "(123)-456-7890" format. So when I put 1234567890 in the filter textbox, there is no result. I saw an example to apply a phone number mask for kendo text box. Is it possible to apply one for a grid column filter?
