The Diagram provides editing options which enable you to add tools and shapes to it, and use its layout options.

Getting Started

To enable the editing functionality of the Diagram:

  1. Configure the DataSource for remote CRUD operations. You have to include the model declaration. The Id is mandatory to indicate which of the fields is the unique identifier.

        .DataSource(d => d
            .Model(m =>
                m.Id(s => s.Id);
                m.Field(s => s.Id).Editable(false);
                m.Field(s => s.JobTitle);
                m.Field(s => s.Color);
            .Read("ReadShapes", "DiagramData")
            .Create("CreateShape", "DiagramData")
            .Destroy("DestroyShape", "DiagramData")
            .Update("UpdateShape", "DiagramData")
        <kendo-diagram name="diagram">
            <hierarchical-datasource server-operation="false" type="DataSourceTagHelperType.Ajax">
                    <read url="@Url.Action("ReadShapes", "DiagramData")" />
                    <create url="@Url.Action("CreateShapes", "DiagramData")" />
                    <destroy url="@Url.Action("DestroyShapes", "DiagramData")" />
                    <update url="@Url.Action("UpdateShapes", "DiagramData")" />
                    <hierarchical-model id="Id">
                            <field name="Id" editable="false" type="number"></field>
                            <field name="JobTitle" type="string"></field>
                            <field name="Color" type="string"></field>
  2. Configure the ConnectionsDataSource for remote CRUD operations. Without setting the ConnectionsDataSource, editing is disabled.

        .ConnectionsDataSource(d => d
            .Model(m =>
                m.Id(c => c.Id);
                m.Field(c => c.Id).Editable(false);
                m.Field(c => c.Text).Editable(false);
                m.From(c => c.FromShapeId);
                m.To(c => c.ToShapeId);
                m.FromX(c => c.FromPointX);
                m.FromY(c => c.FromPointY);
                m.ToX(c => c.ToPointX);
                m.ToY(c => c.ToPointY);
            .Read("ReadConnections", "DiagramData")
            .Create("CreateConnection", "DiagramData")
            .Destroy("DestroyConnection", "DiagramData")
            .Update("UpdateConnection", "DiagramData")
        <kendo-diagram name="diagram">
            <connections-datasource server-operation="false" type="DataSourceTagHelperType.Ajax">
                    <read url="@Url.Action("ReadConnections", "DiagramData")" />
                    <create url="@Url.Action("CreateConnections", "DiagramData")" />
                    <destroy url="@Url.Action("DestroyConnections", "DiagramData")" />
                    <update url="@Url.Action("UpdateConnections", "DiagramData")" />
                    <model id="id">
                            <field name="id" editable="false" type="number"></field>
                            <field name="text" editable="false" type="string"></field>
                            <field name="from" from="FromShapeId" type="number"></field>
                            <field name="to" from="ToShapeId" type="number"></field>
                            <field name="fromX" from="FromPointX" type="number"></field>
                            <field name="fromY" from="FromPointY" type="number"></field>
                            <field name="toX" from="ToPointX" type="number"></field>
                            <field name="toY" from="ToPointY" type="number"></field>

Model Fields

The shape model provides the following fields:

  • id (Number)—A mandatory field. Represents the unique identifier of the shape. A shape without an id field will not be connected.
  • type (String)—The shape type.
  • text (String)—The shape text.
  • x (Number)—The x position of the shape.
  • y (Number)—The y position of the shape.
  • width (Number)—The shape width.
  • height (Number)—The shape height.

Each model field gets updated upon user interaction.
