height

Specifies the widget's height.

Type:

|

|

Return Value:

|

The widget's height.

Default Value: undefined

This option accepts a value of one of the following types:

Number
The height in pixels.
String
A CSS-accepted measurement of height. For example, "55px", "80%", "auto", "inherit".
Function
A function returning either of the above. For example:
JavaScript
```
height: function() {
    return window.innerHeight / 1.5;
}
```

hint

Specifies text for a hint that appears when a user pauses on the widget.

Type:

Default Value: undefined

hoverStateEnabled

Specifies whether the widget changes its state when a user pauses on it.

Type:

Default Value: false

isValid

Specifies whether the editor's value is valid.

Type:

Default Value: true

In Knockout apps, you may need to inform a user about an error that occurred during the validation of a view model field. For this purpose, set the editor's isValid option to the isValid value of the dxValidator that validates this field. To show an error message, set the editor's validationError option to the dxValidator's validationError value.

JavaScript

var editorValue = ko.observable("").extend({
    dxValidator: {
        validationRules: [{
            type: "required",
            message: "Specify this value"
        }]
    }
});
var viewModel = {
    editorOptions: {
        value: editorValue,
        isValid: editorValue.dxValidator.isValid,
        validationError: editorValue.dxValidator.validationError
    }
};

The editor's isValid and validationError options should also be specified when using a custom validation engine. In this instance, the validation result will be displayed for the editor by the means of the DevExtreme Validation UI.
