ASPxTreeView.JSProperties Property

Allows you to pass data from the server to the client side.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

public Dictionary<string, object> JSProperties { get; }

VB.NET

Public ReadOnly Property JSProperties As Dictionary(Of String, Object)

Property Value

Type	Description
Dictionary<String, Object>	The collection of property names and their values.

Remarks

The JSProperties property allows you to pass a collection of name/value pairs from the server side to the client side (but not vice versa). A property can be accessed on the client side once it is declared. The only requirement is that property names must begin with the cp prefix (client property) to avoid rewriting a control’s base properties.

The following value types are supported:

• null
• DBNull
• ValueType
• string
• IDictionary
• IEnumerable

ASPX

<dx:ASPxTreeView ID="dxTreeView"  ClientInstanceName="tree" runat="server">

C#

// Specify a new property on the server side.
dxTreeView.JSProperties["cpMyAttribute"] = "1"

VB.NET

' Specify a new property on the server side.
dxTreeView.JSProperties("cpMyAttribute") = "1"

JS

// After a property has been specified, you can access its value on the client side.
var i = tree.cpMyAttribute;
