Hi

I dont know the interpretation of:

   var match = ko.utils.arrayFirst(self.Prop_GridControl.Prop_SelectedItems(), function (item) {
                return "ESPE0001" != item.IdEstado;
            });
            return match === undefined || match === null;

In the code:

self.Trigger_SeleccionGrilla = ko.observable();
    self.Comp_PuedeEliminar = ko.computed(function () {
        self.Trigger_SeleccionGrilla();
        var hasSelection = self.Prop_GridControl.Prop_SelectedItems().length > 0;
        if (hasSelection) {
            var match = ko.utils.arrayFirst(self.Prop_GridControl.Prop_SelectedItems(), function (item) {
                return "ESPE0001" != item.IdEstado;
            });
            return match === undefined || match === null;
        } else {
            return false;
        }        
    }, self);
