Columns in Blazor Kanban Component

15 Dec 202224 minutes to read

The Kanban columns represents each stage of the process. The column definitions are used as the DataSource schema in the Kanban. The Kanban operations such as drag-and-drop, swimlane, and toggle columns are performed based on column definitions.

Single-key mapping

Kanban columns are categorized by mapping the key from the datasource using the KeyField property. The corresponding value in the datasource is mapped inside the columns KeyField. Based on this categorization, Kanban columns are split on this board.

NOTE

The KeyField property is mandatory to render the columns in the Kanban board.

Blazor Kanban Column with Multi Key

Header text

You can provide the column header text of Kanban columns using the HeaderText property. If you have not specified any header text, it will render the header without any text.

Header template

You can customize the column header with Template property as shown in the following code.

To get start quickly with Blazor Kanban component using Templates, you can check on this video.

Customizing Column Header in Blazor Kanban

Toggle columns

Kanban allows to expand or collapse its columns using AllowToggle in KanbanColumn. When the property is enabled, it will render the expand or collapse icon to the column header.

NOTE

By default, collapsed column width is set to 50px.

Blazor Kanban with Toggle Columns

Initially collapsed column

By default, all columns are on expanded state when loading the Kanban board initially. But, you can render the columns with collapsed state using the IsExpanded property.

NOTE

The IsExpanded property only works when enabling the AllowToggle property on particular column.

In the following example, the Backlog column is collapsed on initialization of Kanban board.
