Reordering

By default, users may reorder columns by dragging their headers into new positions.

You may prevent users from reordering columns by setting the grid's allowDragging property to 'None'. You may also prevent dragging specific columns by setting the column's allowDragging property to false.

For example, the grid below allows reordering all columns except 'ID.

Note: To enable drag/drop operations on touch devices, your project should import the '@mescius/wijmo.touch' module.
