    Please note that this functionality will work only for regular form
    posting. Scenarios where Kendo UI MVVM or AngularJS are used, the model
    field will be set to the masked value, because the available
    bindings/directives use widget's value method.


    Are there any plans to change that ? I am using MVVM together with a lot of maskedtextboxes and so for me the maskedTextBoxes are useless.

    Hello Dirk,

    I would suggest you us a custom MVVM binding if you would like to use the raw method instead of value. Here is a demo that demonstrates how to accomplish this task:
    We do not have any specific plans to change the current MVVM value binding behavior when used with MaskedTextBox. The proper solution for the time being is to use the shared custom MVVM binding.

    The approach I took was to just extend the control, I just link this js file after the kendo.maskedtextbox.js file. (This was written for the 2014.3 version, but it wouldn't be difficult to modify for the current version.). This approach changes the implementation to match other kendo controls that post data in a different way than they display.

    (function ($) {
        var kendo = window.kendo,
            ui = kendo.ui,
            MaskedTextBox = ui.MaskedTextBox;
        var extendedMaskedTextBox = MaskedTextBox.extend({
            init: function (element, options) {
                var self = this,
                    id = element.id,
                    name = element.name,
                    suffix = '_input',
                    input = $(kendo.template(self._inputTemplate)({ id: id, name: name }));
                self.input = input;
                // base call to widget initialization
                MaskedTextBox.fn.init.call(this, element, options);
                element = self.element;
                // swap the data
                element.attr({ id: id + suffix, name: name + suffix });
                element.on('keyup', $.proxy(self.updateValue, self));
                element.on('blur', $.proxy(self.updateValue, self));
                // is this covered by keyup?
                element.on('paste', $.proxy(self.updateValue, self));
            updateValue: function () {
                var self = this,
                    element = self.element,
                    input = self.input,
                    options = self.options,
                    unmasked = self._unmask(element.val(), 0);
                if (options.postMaskedValue) {
                } else {
                    input.val(unmasked.replace(new RegExp(options.promptChar, "g"), ""));
            _mask: function (start, end, value, backward) {
                var self = this;
                MaskedTextBox.fn._mask.call(self, start, end, value, backward);
            _inputTemplate: '<input id="#= id #" name="#= name #" type="text" style="display:none" />',
            options: {
                sourceAction: ''
