  I have formula evaluating a value in Sheet1 and formula depends on cell in Sheet2.
  
  When I set cell value in Sheet2 I only get notification about the value I set but do not get notification about value change in Sheet1.
  
  Why?

  Hello Alexei,
  
  We do not face the issue at our end with a stripped-down sample. Please find the attached sample implementing the same.
  
  If you are doing anything else then please let us know and modify the sample accordingly.

  Hi Prabhat,
  
  I've updated your sample to load workbook from disk instead of creating in-memory.
  I used the workbook file created by your sample.
  
  The modified example reproduces my problem: Workbook_SheetChange does not get called with the changes in Sheet1!A6 (with formula in it).

  Hello,
  
  As per the developers, the current behavior is by design, for good performance, we only fire event for cells which value is changed by the user, if you want to know which cells is changed by formulas, you can call IRange.GetDependents() to get the cells.
  
  Please find the attached sample implementing the same.
