React SelectBox Props
acceptCustomValue
Specifies whether the UI component allows a user to enter a custom value. Requires the onCustomItemCreating handler implementation.
accessKey
The value of this property will be passed to the accesskey
attribute of the HTML element that underlies the UI component.
buttons[]
Built-in buttons should also be declared in this array. You can find an example in the following demo:
dataSource
The SelectBox works with collections of objects or string
, number
, or boolean
values.
Depending on your data source, bind the SelectBox to data as follows. In each case, also specify the valueExpr, displayExpr, or both if the data source provides objects.
Data Array
Assign the array to the dataSource option.Read-Only Data in JSON Format
Set the dataSource property to the URL of a JSON file or service that returns JSON data.OData
Implement an ODataStore.Web API, PHP, MongoDB
Use one of the following extensions to enable the server to process data according to the protocol DevExtreme UI components use:Then, use the createStore method to configure access to the server on the client as shown below. This method is part of DevExtreme.AspNet.Data.
jQuery
JavaScript$(function() { let serviceUrl = "https://url/to/my/service"; $("#selectBoxContainer").dxSelectBox({ // ... dataSource: DevExpress.data.AspNet.createStore({ key: "ID", loadUrl: serviceUrl + "/GetAction", insertUrl: serviceUrl + "/InsertAction", updateUrl: serviceUrl + "/UpdateAction", deleteUrl: serviceUrl + "/DeleteAction" }) }) });

App.jsimport React from 'react'; import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import CustomStore from 'devextreme/data/custom_store'; import { createStore } from 'devextreme-aspnet-data-nojquery'; import SelectBox from 'devextreme-react/select-box'; const serviceUrl = "https://url/to/my/service"; const store = createStore({ key: "ID", loadUrl: serviceUrl + "/GetAction", insertUrl: serviceUrl + "/InsertAction", updateUrl: serviceUrl + "/UpdateAction", deleteUrl: serviceUrl + "/DeleteAction" }); class App extends React.Component { render() { return ( <SelectBox ... dataSource={store} /> ); } } export default App;
Any other data source
Implement a CustomStore.
Regardless of the data source on the input, the SelectBox always wraps it in the DataSource object. This object allows you to sort, filter, group, and perform other data shaping operations. To get its instance, call the getDataSource() method.
Review the following notes about data binding:
Do not specify the items property if you specified the dataSource, and vice versa.
Data field names cannot be equal to
this
and should not contain the following characters:.
,:
,[
, and]
.The stores and DataSource have methods to process and update data. However, the methods do not allow you to perform particular tasks (for example, replace the entire dataset, reconfigure data access at runtime). For such tasks, create a new array, store, or DataSource and assign it to the dataSource property as shown in the articles about changing properties in jQuery, Angular, React, and Vue.
deferRendering
Specifies whether to render the drop-down field's content when it is displayed. If false, the content is rendered immediately.
displayExpr
Set this property to the name of a data field that provides displayed values...
displayExpr: "name"
... or to a function that returns the displayed value:
displayExpr: function(item) { // "item" can be null return item && 'ID: ' + item.id + ', Name: ' + item.name; }
Leave this property unspecified or set it to this
if the data source contains primitives.

itemComponent
An alias for the itemTemplate property specified in React. Accepts a custom component. Refer to Using a Custom Component for more information.
itemRender
An alias for the itemTemplate property specified in React. Accepts a rendering function. Refer to Using a Rendering Function for more information.
items
The items array can contain:
- Objects with fields described in this section
- Objects with any other fields. In this case, specify the itemTemplate.
If you need to update the UI component items, reassign the entire items array as shown in the following example:
selectBoxInstance.option('items', newItems);
As an alternative to items, you can use the dataSource property. It accepts the DataSource object, whose underlying stores provide an API that allows you to update individual items without reassigning the entire item collection.
minSearchLength
The minimum number of characters that must be entered into the text box to begin a search. Applies only if searchEnabled is true.
noDataText
The SelectBox component evaluates the noDataText property's value. This evaluation, however, makes the SelectBox potentially vulnerable to XSS attacks. To guard against these attacks, encode the HTML markup before you assign it to the noDataText property. Refer to the following help topic for more information: Potentially Vulnerable API - noDataText.

readOnly
When this property is set to true, the following applies:
- The editor's value cannot be changed using the UI.
- Built-in action buttons are invisible.
Custom action buttons are visible but disabled. If a button should not be disabled, set its disabled property to false:
jQuery
index.js$(function() { $("#selectBoxContainer").dxSelectBox({ // ... buttons: [{ name: "myCustomButton", location: "after", options: { onClick: function(e) { // ... }, disabled: false } }] }); });

You can also hide a custom action button when the UI component becomes read-only. Set the button's visible property to false in the onOptionChanged function. To get the button, use the getButton(name) method:
jQuery
index.js$(function() { $("#selectBoxContainer").dxSelectBox({ // ... buttons: [{ name: "myCustomButton", // ... }], onOptionChanged: function(e) { if(e.name == "readOnly") { const myButton = e.component.getButton("myCustomButton"); myButton.option("visible", !e.value); // Hide the button when readOnly: true } } }); });

rtlEnabled
When this property is set to true, the UI component text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.
DevExpress.config({ rtlEnabled: true });
searchEnabled
See Also
searchExpr
Specifies the name of a data source item field or an expression whose value is compared to the search criterion.
In most cases, you should pass the name of a field by whose value data items are searched. If you need to search elements by several field values, assign an array of field names to this property.
searchExpr: ["firstName", "lastName"]
For more information on searching, refer to the Search API section of the Data Layer article. For information on getters, refer to the Getters and Setters section of the Data Layer article.
searchTimeout
Specifies the time delay, in milliseconds, after the last character has been typed in, before a search is executed.
showDataBeforeSearch
Specifies whether or not the UI component displays unfiltered values until a user types a number of characters exceeding the minSearchLength property value.
If this property is disabled, the UI component does not display values until the number of typed characters exceeds the minSearchLength value, otherwise it displays all values regardless of the specified filtering condition.
stylingMode
The following styles are available:
You can also use the global editorStylingMode setting to specify how the text fields of all editors in your application are styled.

The value of this property will be passed to the tabindex
attribute of the HTML element that underlies the UI component.
validationError
Information on the broken validation rule. Contains the first item from the validationErrors array.
validationMessageMode
Specifies how the message about the validation rules that are not satisfied by this editor's value is displayed.
value
Specifies the currently selected value. May be an object if dataSource contains objects and valueExpr is not set.
valueChangeEvent

This property accepts a single event name or several names separated by spaces.
The recommended events are "keyup", "blur", "change", "input", and "focusout", but you can use other events as well.
See Also
valueExpr
Specifies which data field provides unique values to the UI component's value.
Always set this property if the dataSource contains objects. Alternatively, you can specify the key in the store.
See Also
