JavaScript/jQuery ContextMenu Options
accessKey
The value of this property will be passed to the accesskey
attribute of the HTML element that underlies the UI component.
activeStateEnabled
The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.
Use this property when you display the component on a platform whose guidelines include the active state change for UI components.
animation
closeOnOutsideClick
Use the hideOnOutsideClick property instead.
Event (jQuery or EventObject)
The event that caused UI component closing. It is a EventObject or a jQuery.Event when you use jQuery.
dataSource
The ContextMenu works with collections of string
values or objects.
Depending on your data source, bind ContextMenu to data as follows. If the data source provides objects, also specify the itemTemplate. You can skip this part if the objects contain fields described in the items section.
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.
JavaScript- $(function() {
- let serviceUrl = "https://url/to/my/service";
- $("#contextMenuContainer").dxContextMenu({
- // ...
- dataSource: DevExpress.data.AspNet.createStore({
- key: "ID",
- loadUrl: serviceUrl + "/GetAction",
- insertUrl: serviceUrl + "/InsertAction",
- updateUrl: serviceUrl + "/UpdateAction",
- deleteUrl: serviceUrl + "/DeleteAction"
- })
- })
- });
Any other data source
Implement a CustomStore.
Regardless of the data source on the input, the ContextMenu 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 are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Get and Set Properties.
disabledExpr
Specifies the name of the data source item field whose value defines whether or not the corresponding UI component item is disabled.
elementAttr
Specifies the global attributes to be attached to the UI component's container element.
height
This property accepts a value of one of the following types:
Number
The height in pixels.String
A CSS-accepted measurement of height. For example,"55px"
,"20vh"
,"80%"
,"inherit"
.Function (deprecated since v21.2)
Refer to the W0017 warning description for information on how you can migrate to viewport units.
hideOnOutsideClick
Event (jQuery or EventObject)
The event that caused UI component hiding. It is a EventObject or a jQuery.Event when you use jQuery.
The function passed to this property enables you to specify a custom condition for UI component hiding. For instance, you can prevent hiding until a user clicks a certain element.
- $(function () {
- $("#contextMenuContainer").dxContextMenu({
- // ...
- hideOnOutsideClick: function(e) {
- return e.target === $("#someElement").get()[0];
- }
- });
- });
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:
- contextMenuInstance.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.
