System.ArgumentException: Parameter is not valid. RRS feed

  • Question

  • Hi there,

    I get randomly this exception. Not sure if this has to do with syncfusion or native .net controls issues. It pops up with the window and the user gets stuck. Would be great help if any solution offered here and also can we also swallow and not show message for such issues though it is not a good practice. Having issues logged helps for better user satisfaction.

    System.ArgumentException: Parameter is not valid.

  • Hi GB,

    It seems there is a problem in one of your Suncfusion controls. 

    Probably is the best approach to contact their forum.
