WPF Performance - Finding Source of Layout Pass Invocation -

is there way figure out why/what invoked wpf layout pass control?

i tracking amount of arrange overrides being called our main user control:

public partial class myview {     private ulong _arrangecount;     protected override size arrangeoverride(size arrangebounds)     {         debug.writeline($"ttv - arrangeoverride - {_arrangecount++}");         return base.arrangeoverride(arrangebounds);     } } 

the counts of loading view 40! complex ui (data grids nested, 100's of cells , custom templates columns,cells,rows) taking seconds! (a large portion of time spent in measure/arrange)

is there way find out source of each pass?

at moment removing things user control , trying figure out causing bunch of these.

i did notice there lot of things stored in effective values, because of bindings in styles/templates inside main control resource dictionaries?

would update effective values (even though of them not affect parent control, cause measure/arrange invoked?)

i have managed cache measure size follows seems have helped on measure side, arrange, cannot same not arrange correctly, after content has been bound!

    private size _lastmeasureconstraint;      private ulong _measurecount;     protected override size measureoverride(size constraint)     {         if (_lastmeasureconstraint == constraint)             return constraint;          debug.writeline($"ttv - measureoverride - {_measurecount++}");         _lastmeasureconstraint = constraint;         return base.measureoverride(constraint);     }
