Validate Constraints
This sample validates the number of cards in the particular column or swimlane using the constraintType property. This property contains two types: Column: Validates the number of cards based on the particular column. By default, column validation is applied to Kanban board. Swimlane: Validation applies based on number of cards in a particular column cell and swimlane. This sample contains the following properties: Columns: You can choose a column and set maximum and minimum limit to the selected column. minCount: Minimum limit of cards required for each column. If the cards count do not reach the minimum limit, it will indicate the validation failed state. maxCount: Maximum limit of cards per column. If the cards count exceeds the maximum limit, it will indicate the validation failed state.
