property SwimLane.AllowDesignHeader as AllowDesignHeaderEnum
Indicates that lanes and their parents shows on separate headers while cursor hovers the pool's header.

TypeDescription
AllowDesignHeaderEnum An AllowDesignHeaderEnum expression that determines how the pool's header is shown ( while cursor hovers it ).
By default, the AllowDesignHeader property is exDesignHeaderDefault, so the design-header ( parent-header ) is shown when the user hovers the header. The design-header ( parent-header ) is not displayed, if the DesignMode property is exDesignLock. For instance, use the AllowDesignHeader property exDesignHeaderSingle to prevent creating parent-child lanes. The Background(exPoolHorizontalHeaderBackColor) or Background(exPoolVerticalHeaderBackColor) indicates the default visual-appearance for the pool's horizontal or vertical header. For instance, you can use the AllowDesignHeader property on exDesignHeaderSingle, so the user can not create no sub-lanes at runtime. The Parent property retrieves the parent of the lane.
