Column fields are present in the dataSource schema and it is rendering cards based its mapping column values.

Key Mapping

To render Kanban with simple cards, you need to map the dataSource fields to Kanban cards and columns.

NOTE

  1. If the column with keyField is not in the dataSource and key values specified will not available in column values, then the cards will not be rendered.
  2. If the fields.content is not in the dataSource, then empty cards will be rendered.

The following code example describes the above behavior.

  • html
  • <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
    	<%@ taglib prefix="ej" uri="/WEB-INF/EJ.tld" %>
    	<%@ page import="com.syncfusion.*" %><%@ page import="datasource.GetJsonData" %> 
        <body>
    	<div class="cols-sample-area"><%
        GetJsonData obj=new GetJsonData();
        Object data = obj.GetKanbanJson();
        request.setAttribute("KanbanDataSource",data);%>
        <ej:kanban id="Kanban" keyField="Status" dataSource="${KanbanDataSource}">
    			<ej:kanban-fields content="Summary" primaryKey="Id"></ej:kanban-fields>
    			<ej:kanban-columns>
    				<ej:kanban-column headerText="Backlog" key="Open"></ej:kanban-column>
    				<ej:kanban-column headerText="In Progress" key="InProgress"></ej:kanban-column>
    				<ej:kanban-column headerText="Testing" key="Testing"></ej:kanban-column>
    				<ej:kanban-column headerText="Done" key="Close"></ej:kanban-column>
    			</ej:kanban-columns>
        </ej:kanban>
    	</div>
        </body>
        </html>

    The following output is displayed as a result of the above code example.

    Multiple Key Mapping

    You can map more than one datasource fields as key values to show different key cards into single column. For e.g , you can map “Validate,In progress” keys under “In progress” column.

    The following code example and screenshot which describes the above behavior.

  • html
  • <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>

    	<div class="cols-sample-area"><%
        GetJsonData obj=new GetJsonData();
        Object data = obj.GetKanbanJson();
        request.setAttribute("KanbanDataSource",data);%>
        <ej:kanban id="Kanban" keyField="Status" allowTitle="true" dataSource="${KanbanDataSource}">
    			<ej:kanban-fields content="Summary" primaryKey="Id"></ej:kanban-fields>
