WIP Validation in JavaScript Kanban control

Validate particular column using the minCount or maxCount properties. The corresponding columns gets different appearance when validation fails. In default layout, constraintType property accept only Column type. In swimlane layout, accept both Column and Swimlane constraint type.

There are two types of constraints:

  1. Column
  2. Swimlane

By default, the column count validation is performed based on Kanban columns.

Minimum card limit

The minCount property is used to specify the minimum cards hold on particular column or swimlane cell. If the column or swimlane total card count falls short of the minimum count value, it shows the column or cell background colour with validation fails.

Maximum card limit

The maxCount property is used to specify the maximum cards hold on particular column or swimlane cell. If the column or swimlane cell total card count exceeds the maximum count value, it shows the column or cell background colour with validation fails.
