property SwimLane.AllowResizeLane as AllowKeysEnum
Specifies the combination of keys that allows the user to resize the lanes of the pool.

TypeDescription
AllowKeysEnum An AllowKeysEnum expression that specifies the keys combination so the user can resize the lane from the cursor. 
By default, the AllowResizeLane property is exLeftClick, which indicates that with a simple click on the lane's border, the user can resize the lane. Use the AllowResizeLane property to specify whether the lane can be resized at runtime.  The AllowMoveLane property specifies the keys combination so the user can move the lane from the cursor. Set the AllowResizeLane property on exDisallow, to prevent user to resize any lane in the surface. The control fires the LayoutStartChanging(exResizeLane) / LayoutEndChanging(exResizeLane) event when the user resizes the object.
