  I am using collectionView to bind data to flex grid Angular2 , I have business requirement to do validation on grid cell.

  CollectionView.getError call back function does not tells exactly if there are any errors are not, What I want to know is how to find out if collectionView has any errors or not ?

  Hi,
  
  CollectionView’s getError method is used for setting validation condition for CollectionView data and can show error in FlexGrid based on condition.
  
  Please refer to the following demo sample that implements the same:

  But my scenario is to disable/enable button if there are any errors on collection View . I did not find any property which returns saying CollectionView has error or not ?

  Hi,
  
  We are sorry, there is no properties or method for this. You need to check manually on FlexGrid initialized event.

  You can get cell data using getCellData() method.

  Hello,
  
  Please find the attached sample that set the font color to red for a cell with an error with itemFormatter.

  You can check error in the same way in initialized event if you would like to verify the collectionView only once.

  Thanks,
