I use Telerik Kendo Grid editing-inline.
I want to hide certain columns when editing popup the number of columns.
You can use the edit event of the grid to hide some element from the popup window:
$("#grid").kendoGrid({
edit: function(e) {
e.container.find(".k-edit-label:first").hide();
e.container.find(".k-edit-field:first").hide();
}
});
