Moving Panels in React Dashboard Layout component

05 May 2021 / 1 minute to read

Other than drag and drop, it is possible to move the panels in Dashboard Layout programmatically. This can be achieved using movePanel method. The method is invoked as follows,

movePanel(id, row, col)

Where,

id - ID of the panel which needs to be moved.
row - New row position for moving the panel.
col - New column position for moving the panel.

Each time a panel’s position is changed(Programmatically or through UI interaction), the Dashboard Layout’s change event will be triggered.

The following sample demonstrates moving a panel programmatically to a new position in the Dashboard Layout’s created event.
