  ClientScript.RegisterStartupScript error

  Feb 08, 2013 08:21 AM|LINK

  I have a class that i use to create script to use jNotify in my ASP.Net Application which works well without adding delay time.

  But after adding delay time it generate error.

  Below is my class

  Public Shared Sub ShowWarningMesage(ByVal _page As Page, ByVal _message As String, _
                                          ByVal delayTime As Integer)
          _page.ClientScript.RegisterStartupScript(_page.GetType(), "notificationScript",
                                                   "<script type='text/javascript'>  $(document).ready(function () { $.jnotify('" +
                                                   _message + "', 'warning', " + delayTime + "); });</script>")
  
      End Sub

  This is how i call it in my page

   NotificationHelper.ShowWarningMesage(Me.Page, "Message Here", 5000)
  
  This is error I get
  
  

  Input string was not in a correct format.

  Line 71:     Public Shared Sub ShowErrorMesage(ByVal _page As Page, ByVal _message As String, _
  Line 72:                                       ByVal delayTime As Integer)
  Line 73:         _page.ClientScript.RegisterStartupScript(_page.GetType(), "notificationScript",
  Line 74:                                                  "<script type='text/javascript'>  $(document).ready(function () { $.jnotify('" +
  Line 75:                                                  _message + "', 'error', " + delayTime + "); });</script>")

  It's because you were mixing types.  As delayTime was numeric, when you did "+" it thought you wanted to add rather than concatinate, so tried to convert what was to the left of the "+" into a numeric format but couldn't.  By converting delayTime to a string, you are now using "+" on two strings so the compiler is in no doubt that you want to concatinate and not add.
