Swim lanes

Swim lanes are a horizontal categorization of issues in the Kanban control which brings transparency to the workflow. This can be enabled by mapping the swimlaneKey to appropriate column name in the dataSource.

The following code example describes the above behavior.

  • html
  • <div id='Kanban'></div>
  • javascript
  • $(function () {
            var data = ej.DataManager(window.kanbanData).executeLocal(ej.Query().take(30));
            
            $("#Kanban").ejKanban(
                {
                    dataSource: data,
                    columns: [
                        { headerText: "Backlog", key: "Open" },
                        { headerText: "In Progress", key: "InProgress" },
                        { headerText: "Done", key: "Close" }
                    ],
                    keyField: "Status",
                    fields: {
                        content: "Summary",
                        primaryKey: "Id",
                        swimlaneKey: "Assignee",
                        imageUrl: "ImgUrl"
                    }
                });
        });

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

    Customized swimlane header text

    You can change the swimlane row header text using the swimlane headers property. In this property, the text is changed using the text property and the corresponding value is mapped into the key property based on swimlaneKey datasource mapping.

    Refer to the following code example.

  • html
  • <div id='Kanban'></div>
  • javascript
  • var kanbanData = [
            { Id: 6, Status: "Close", Summary: "Arrange a web meeting with the customer to get the login page requirements.", Type: "Others", Priority: "Low", Tags: "Meeting", Estimate: 2, Assignee: "Janet", ImgUrl: "/images/kanban/6.png", RankId: 1 },

        $("#Kanban").ejKanban({
            dataSource: kanbanData,
            columns: [
                { headerText: "Backlog", key: "Open" },
                { headerText: "InProgress", key: "InProgress" },
                { headerText: "Done", key: "Close" }
            ],
            keyField: "Status",
            allowTitle: true,
            fields: {

        });

    Empty swimlane row on Kanban board

    You can create an empty swimlane row by enabling the showEmptySwimlane property based on swimlane headers key value mapping. If no data is present, then the empty swimlane row is rendered on the Kanban board based on the specified swimlane headers key.

    Refer to the following code.

  • html
  • <div id='Kanban'></div>
  • javascript
  • var kanbanData = [
            { Id: 8, Status: "Close", Summary: "Login page validation", Type: "Story", Priority: "Release Breaker", Tags: "Validation,Fix", Estimate: 2.5, Assignee: "Andrew Fuller", ImgUrl: "/images/kanban/8.png", RankId: 2 },

            { Id: 10, Status: "InProgress", Summary: "Test the application in the IE browser.", Type: "Story", Priority: "Low", Tags: "Testing,IE", Estimate: 5.5, Assignee: "Andrew Fuller", ImgUrl: "/images/kanban/4.png", RankId: 3 }];
        $("#Kanban").ejKanban({
            dataSource: kanbanData,
            columns: [
                { headerText: "Backlog", key: "Open" },
                { headerText: "InProgress", key: "InProgress" },
                { headerText: "Done", key: "Close" }
            ],
            keyField: "Status",
            allowTitle: true,
            fields: {
                content: "Summary",
                primaryKey: "Id",
                swimlaneKey: "Assignee",
            },
            swimlaneSettings: {
                showEmptySwimlane: true,
                headers: [{ text: 'Andrew', key: 'Andrew Fuller' },
                    { text: 'Janet', key: 'Janet Leverling' }]
                },
            });

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

    Drag And Drop between swim lanes

    You can set ‘allowDragAndDrop’ property of ‘swimlaneSettings’ as true to enable Drag and Drop between the swim lanes.

    If a card is to be dragged in the same swim lane, only a droppable target cell is added to the dotted line border. If a card is dragged from one swim lane to another, all the Kanban cells will be added to the dotted line borders, except the dragged card cell.

    The following code example describes the above behavior.

  • html
  • <div id='Kanban'></div>
  • javascript
  • $(function () {
            var data = ej.DataManager(window.kanbanData).executeLocal(ej.Query().take(30));
            
            $("#Kanban").ejKanban(
                {
                    dataSource: data,
                    columns: [
                        { headerText: "Backlog", key: "Open" },
                        { headerText: "In Progress", key: "InProgress" },
                        { headerText: "Done", key: "Close" }
                    ],
                    keyField: "Status",
                    fields: {
                        content: "Summary",
                        primaryKey: "Id",
                        swimlaneKey: "Assignee",
                        imageUrl: "ImgUrl"
                    },
                    swimlaneSettings:{
                        allowDragAndDrop: true,
                    },
                });
        });

    Unassigned swim lane group

    Unassigned swim lane feature provides option to group some common swim lane key values as separate swim lane group. You can enable and disable this behavior using the property enable.
    User can use default common key values or user defined key values.

    •	Using default values
    •	Using user defined values
    

    NOTE

    By default, given common keys are grouped under the swim lane name “Unassigned”, user can customize the name using localization.

    Using default values

    By default, the swim lane keys of card which is having null, undefined, empty string (“”) values will be grouped as unassigned category when enable property is set as true on unassignedGroup.

    The following code example describes the above behavior.

  • html
  • <div id='Kanban'></div>
  • javascript
  • window.kanbanData = [{ Id: 1, Status: "Open", Summary: "Analyze the new requirements gathered from the customer.", Type: "Story", Priority: "Low", Tags: "Analyze, Customer", Estimate: 3.5, Assignee: "Andrew Fuller", ImgUrl: "../content/images/kanban/2.png", RankId: 1 }, { Id: 2, Status: "InProgress", Summary: "Improve application performance", Type: "Improvement", Priority: "Normal", Tags: "Improvement", Estimate: 6, Assignee: "Andrew Fuller", ImgUrl: "../content/images/kanban/2.png", RankId: 1 }, { Id: 3, Status: "Open", Summary: "Arrange a web meeting with the customer to get new requirements.", Type: "Others", Priority: "Critical", Tags: "Meeting", Estimate: 5.5, Assignee: undefined, RankId: 2 }, { Id: 4, Status: "InProgress", Summary: "Fix the issues reported in the IE browser.", Type: "Bug", Priority: "Release Breaker", Tags: "IE", Estimate: 2.5, Assignee: null, RankId: 2 }, { Id: 5, Status: "Close", Summary: "Fix the issues reported by the customer.", Type: "Bug", Priority: "Low", Tags: "Customer", Estimate: "3.5", Assignee: "", RankId: 1 }];
        
        $(function () {
             var data = ej.DataManager(window.kanbanData).executeLocal(ej.Query().take(5));
             $("#Kanban").ejKanban(
                    {

                            { headerText: "In Progress", key: "InProgress" },
                            { headerText: "Done", key: "Close" }
                        ],

             });
        });
