Swim lanes in ASP.NET Core Kanban Control
13 Jul 202124 minutes to read
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 swimlane-key to appropriate column name in the dataSource.
The following code example describes the above behavior.
<ej-kanban id="KanbanBoard" key-field="Status" dataSource="ViewBag.datasource\">
<e-kanbancolumns>
<e-kanbancolumn header-text="Backlog" key=@(new List<string>(){"Open"})>

<e-kanbancolumn header-text="In Progress" key=@(new List<string>() {"InProgress"})></e-kanbancolumn>
<e-kanbancolumn header-text="Done" key=@(new List<string>() {"Close"})></e-kanbancolumn>
</e-kanbancolumns>

Drag And Drop between swim lanes
You can set allow-drag-and-drop property of [kanbanswimlane-settings] 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.

Unassigned swim lane group
Kanban cards which have null,undefined, empty string(“”) swimlane key values or user specified swimlane key values in the [keys(kanbanswimlane-settings.kanbanunassigned-group.keys)] collection will be grouped under the Unassigned swimlane group.You can enable and disable this behavior using the property [enable(kanbanswimlane-settings.kanbanunassigned-group.enable)] and the default value is true.
Default values in the [keys(kanbanswimlane-settings.kanbanunassigned-group.keys)] collection are null,undefined,empty string(“”).You can also add your own(user-defined) swim-lane key values in the [keys(kanbanswimlane-settings.kanbanunassigned-group.keys)] collection.
Unassigned swim lane group with default values
Kanban cards which have null,undefined, empty string(“”) swimlane key values will be grouped under the Unassigned swimlane group when Unassigned swim lane group is enabled.(set true to [enable(kanbanswimlane-settings.kanbanunassigned-group.enable)] property and the default value is true).
Default values in the [keys(kanbanswimlane-settings.kanbanunassigned-group.keys)] collection are null,undefined,empty string(“”).
