Button Types

You can also specify your own button type and define its CSS rules as shown in the example:

jQuery
index.js
index.css
$(function() {
    $("#button").dxButton({
        // ...
        type: "warning"
    });
});
.dx-button.dx-button-warning {
    background-color: #ffc107;
}
Angular
app.component.html
app.component.css
<dx-button ...
    type="warning"
/>
::ng-deep .dx-button.dx-button-warning {
    background-color: #ffc107;
}
Vue
App.vue
<template>
    <DxButton ...
        type="warning"
    />
</template>

<script>
    // ...
</script>

<style>
    .dx-button.dx-button-warning {
        background-color: #ffc107;
    }
</style>
React
App.js
index.css
function App() {
    return (
        <Button ...
            type="warning" 
        />
    );
};

export default App;
.dx-button.dx-button-warning {
    background-color: #ffc107;
}

Note that buttons have a white background when you move them to the Toolbar. We recommend that you use the 'normal' type for such buttons, otherwise the button text is not visible. You can also define custom CSS rules to override the initial styles.

useSubmitBehavior

Specifies whether the button submits an HTML form.

Type:

Boolean

Default Value: false

If this property is set to true, users can click the button to validate the validation group and submit the HTML form. If the group contains async rules, the form is not submitted until they are checked.

If the onClick event handler is specified, it is executed before validation and form submission.

If you need to cancel form submission, handle a form's submit event.

View Demo

validationGroup

Specifies the name of the validation group to be accessed in the click event handler.

Type:

String

Default Value: undefined

When using a button to validate several editors on a page, the button must "know" in which validation group these editors are located. If the Knockout or AngularJS approach is used, add the button to the div element that represents the target validation group. When using the jQuery approach, specify the validationGroup configuration property for the button. Assign the validation group name specified for the validationGroup property of the validators that extend the editors to be validated.
