JavaScript/jQuery HtmlEditor - mentions

View Demo

If you use DevExtreme ASP.NET MVC Controls, refer to the Bind Controls to Data article.

Depending on your data source, specify this property as described in the following list. The data source can provide string values or objects. In the latter case, also specify the displayExpr and valueExpr.

• Data Array
  Assign the array to the dataSource property.

• 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:

  • DevExtreme.AspNet.Data
  • DevExtreme-PHP-Data
  • devextreme-query-mongodb

  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.

• Any other data source
  Implement a CustomStore.

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;
}

Do not change the default value if the data source contains primitives.
