var tourt = kendo.template('<tr><td>${TotalRegistration=MemberRegistrationCount+GuestRegistrationCount}</td></tr>');
var tourh = '<table id="tourg"><thead><tr><th># Registered</th></tr></thead></table>';
tourngrid = $('#tourg').kendoGrid({ rowTemplate: tourt }).data('kendoGrid');
$('#minUsers').kendoNumericTextBox();
$('#goFilter').click(function() {
tourngrid.dataSource.filter({filter: { field:"TotalRegistration", operator:"ge", value:$('#minUsers').data('kendoNumericTextBox').value()}});
});
Amazingly the assignment in the row template still reports the correct number in the grid column. But it does not execute the filter using that assigned variable defined in the template.
Is there a way to sum two columns and use the result in the grids filter?
