Client-side Data Binding

Generic Team Structure

You can data bind RadDiagram shapes and connections on the client to RadClientDataSource controls since Q1 2015.

Client-side data binding allows for:

  • data updates without postbacks
  • easy integration with various data services
  • flexible client-side development.

The client-side data binding is provided through the following properties:

  • ClientDataSourceID - the server ID of the RadClientDataSource responsible for providing the Shapes data.
  • ConnectionsClientDataSourceID - the server ID of the RadClientDataSource responsible for providing the Connections data.

The shapes and connections data should be in a JSON format with the necessary fields:

  • for Shapes, you need fields with the exact names from The fields of the shape model article. These fields control the type, position and dimensions of the shapes.
  • for Connections, you need fields with the exact names from The fields of the connection model article. These fields associate connections with the shapes.

Note: If you want to customize the shapes yourself, you can get the necessary data from the dataItem object and reconfigure the shapes in either of the following ways:

  • DefaultVB.aspx
  • scripts.js
