Description
Causes the Columns property to be recomputed when the dataset changes or changes are made to individual column objects.
Applications cannot call this protected method. It is called when the Columns property changes or the fields in the dataset change. LayoutChanged recomputes the Columns property after guarding against recursion from the changes to the Columns property that arise in the computation.
LayoutChanged calls AcquireLayoutLock to initiate the changes to Columns. If AcquireLayoutLock does not indicate that the call to LayoutChanged is recursive, LayoutChanged calls EndLayout to perform the actual computation.
