Drag and Drop

By default, allow-drag-and-drop is true. Cards can be transited from one column to another column, by dragging and dropping. And it has drop position indicator which enables easier positioning of cards

NOTE

It is not possible transit cards to other swim lanes through Drag and Drop.

Prioritization of cards

Prioritizing cards is easy with drag-and-drop re-ordering that helps you to categorize most important work at the top. Cards can be categorized with priority by mapping specific database field into priority property.

rank-id defined in the dataSource which is consist priority of cards. The rank-id will be changed while card ordering changes through drag and drop and editing.

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>
        <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>
     <e-kanbanfield content="Summary" primary-key="Id" priority="RankId">
     </e-kanbanfield>
</ej-kanban>

        public string Type { get; set; }
        public string Priority { get; set; }
        public string Tags { get; set; }
        public double Estimate { get; set; }
        public string Assignee { get; set; }
        public string ImgUrl { get; set; }
        public int RankId { get; set; }
    }
}

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

Priority of card

NOTE

For Drag and Drop event handling, please refer this API.

NOTE

If the Priority property is not set in the Kanban fields, the cards are dropped based on the specifying JSON data orders in a particular column.  If not set, drop the card in a particular position based on the previous card Priority value and the next card’s Priority values will change dynamically.
