Defaults to null.

function setValidations(value: [EditValidation|Object])

Note

• You can specify as EditValidation object, while a new EditValidation object will be created internally instead of directly using this object.
• In other words, If change the property of the corresponding object after creating EditValidation object externally and specifying this property, it will not be reflected.

    grid.columnByName('colPrice').setValidations([{
        expression: 'value > 1000',
        level: DataLudi.ValidationLevel.ERROR,
        message: 'The unit price should be greater than 1000.'
    }, {
        callback: function (scope) {
            if (scope.value > 2000) {
                return false;
            }
        },
        level: DataLudi.ValidationLevel.INFO,
        message: 'The unit price should be less than 2000.'
    }]);

    // You can specify only one.
    grid.columnByName('colQuantity').setValidations({
        expression: 'value > 100',
        level: DataLudi.ValidationLevel.ERROR,
        message: 'The quantity should be greater than 100.'
    });
