How can we achieve expand all/ collapse all functionality on Kanban swimlanes?

You can achieve your requirement by grouping the data collection using the “SwimlaneKey” from the WPF SfKanban. If no value is assigned to the SwimlaneKey mapped property in a task, then it will be grouped under the Unassigned swim lane. We have prepared the simple sample, please find the attached sample for the same,

Refer to our UG documentation to know more details about swim lanes in WPF Kanban,

Hi Muniappan,

To make my query clear, I've attached two snapshots below. I need to achieve expanding or collapsing all the swimlane headers at once programmatically. Current grouping by swimlaneKey only expands all swimlane headers at the change of the swimlanKey.

#Regarding Swimelane expand and collapse at programmatically

As per the implementation of SfKanban, there is no support available to expand or collapse the swimelane header programmatically.
