JavaScript/jQuery Diagram - nodes
Allows you to bind the collection of diagram nodes to a data source. For more information, see the Data Binding section.
Type:
Default Value: null
autoLayout
The layout property is in effect when a diagram is bound to a data source using the nodes property.
See Also
autoSizeEnabled
Specifies whether or not a shape size is automatically changed to fit the text when the UI component is bound to a data source.
Type:
Default Value: true
NOTE
If the widthExpr and heightExpr properties are specified, the autosize feature is disabled. The UI component displays shapes based on the provided sizes.
containerChildrenExpr
Specifies the name of a data source field or an expression that provides a container's nested items.
Default Value: 'children'
This property is in effect for "verticalContainer" or "horizontalContainer" nodes.
A function assigned to this property should do the following:
- Return a container's nested items when the value parameter is set to
undefined. - Save item values to a data storage when the value parameter contains a container's nested items. For instance, assign these values to the obj parameter's field to save a container's nested items in your data source.
You can also use the containerKeyExpr property to provide a container's content.
index.js
data.js
$(function() {
$("#diagram").dxDiagram({
nodes: {
dataSource: new DevExpress.data.ArrayStore({
key: "this",
data: orgItems
}),
keyExpr: "id",
parentKeyExpr: "parent_id",
containerChildrenExpr: "children",
},
});
});
var orgItems = [
{

},
{
"id":"113",
"text":"Antonio\nMoreno",
"type":"rectangle",
}]
}
];
containerKeyExpr
Specifies the name of a data source field or an expression that provides a key of a node's parent container node.
Default Value: undefined
A function assigned to this property should do the following:
- Return a node's parent container node when the value parameter is set to
undefined. - Save a container node value to a data storage when the value parameter contains a node's parent container node. For instance, assign this value to the obj parameter's field to save a node's parent container node in your data source.
The parent container node must be of the "verticalContainer" or "horizontalContainer" type.
You can also use the containerChildrenExpr property to provide a container's content.

$(function() {
$("#diagram").dxDiagram({
nodes: {
dataSource: new DevExpress.data.ArrayStore({
key: "this",

},
{
"id":"113",
"text":"Antonio\nMoreno",
"type":"rectangle",
"team": "110"
},
];
customDataExpr
Default Value: undefined
This property links custom data from a data source to a diagram node. The node contains the linked data copied from the data source. Changes in the data are reflected in the diagram history. You can use the UI to undo and redo these changes.
A function assigned to this property should do the following:
- Return a node's new custom data when the value parameter is set to
undefined. - Save a new custom data value to a data storage when the value parameter contains a node's custom data. For instance, assign this value to the obj parameter's field to save a node's custom data in your data source.

Default Value: undefined
A function assigned to this property should do the following:
- Return a node's new z-index when the value parameter is set to
undefined. - Save a new z-index value to a data storage when the value parameter contains a node's z-index. For instance, assign this value to the obj parameter's field to save a node's z-index in your data source.
The z-index specifies the node stack order. A node with greater stack order is in front of a node with a lower stack order.
