Stacked Headers in ASP.NET Core Kanban

24 Sep 20219 minutes to read

The stacked headers help you to group the logical columns in Kanban. It can be shown by setting show-stacked-header as true and by defining stacked-header-rows.

Adding Stacked header columns

To stack columns in stacked header, you need to define [kanbancolumn] property in stacked-header-columns with field names of visible columns.

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="Testing" key=@(new List<string>() { "Testing" }) ></e-kanbancolumn>
        <e-kanbancolumn header-text="Done" key=@(new List<string>() {"Close"}) ></e-kanbancolumn>
     </e-kanbancolumns>
     <e-kanbanfield content="Summary" primary-key="Id">
     </e-kanbanfield>
     <e-kanbanstacked-header-rows>
        <e-kanbanstacked-header-row>
            <e-kanbanstacked-header-columns>
                <e-kanbanstacked-header-column header-text="Unresolved" column=@(new List<string>() {"Backlog","In Progress"})></e-kanbanstacked-header-column>
                <e-kanbanstacked-header-column header-text="Resolved" column=@(new List<string>() {"Testing","Done"})></e-kanbanstacked-header-column>
            </e-kanbanstacked-header-columns>
        </e-kanbanstacked-header-row>
     </e-kanbanstacked-header-rows>
</ej-kanban>
