System.FormatException: Input string was not in a correct format.

  • ofer ebert

    Ohhh then how would we edit the code so that the conversion can be done

    THat function actually deletes a record .

  • Stefan Wenig

    without knowing what "glossData.DataKeys(e.Item.ItemIndex))" does..all I can tell you about your error is that

    "glossData.DataKeys(e.Item.ItemIndex))" produces a string that can not be converted to an integer



  • Shankar K

    Break out that one line of code into 3 lines:

    one line taking the ItemIndex - and validating it.

    One line taking the DataKeys - and validating it.

    One line performing the Integer conversion - and validating it.

    Report any invalidation back, or fix the error through limiting data entry values, or coercion of values (depending on what you are doing).
