Workflows
17 May 202110 minutes to read
Workflows can be defined to set the flow of card moving between the Kanban column statuses and it is applicable to drag and drop and context menu features.
You can set WorkFlow as array of Objects which consists of Key and AllowedTransitions properties. The AllowedTransitions accepts more than one transition of the specific column key mentioned in Key property.
If a card is to be dragged to not allowed transition columns , then not supported warning symbol will be displayed for denoting the error.
The following code example describes the above Workflow functionality.
<ej:Kanban ID="KanbanBoard" runat="server" KeyField="Status">
<WorkFlow>
<ej:KanbanWorkFlow Key="Open" AllowedTransitions="InProgress" />
<ej:KanbanWorkFlow Key="InProgress" AllowedTransitions="Testing,Close" />
</WorkFlow>
<Columns>
<ej:KanbanColumn HeaderText="Backlog" Key="Open" />
<ej:KanbanColumn HeaderText="In Progress" Key="InProgress" />
<ej:KanbanColumn HeaderText="Testing" Key="Testing" />
<ej:KanbanColumn HeaderText="Done" Key="Close" />
</Columns>
<Fields PrimaryKey="Id" Content="Summary"/>
</ej:Kanban>List<Tasks> Task = new List<Tasks>();
