  here is the error message: Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

  It appears that the culprit was the autoeventwireup was set to false, but it needs to be set to true. Could it have been any easier Ok, I am over it now. Thanks for the help all!

  Hope someone can help on this error message above. I search the net to see if this was out there - surprise it was in many forms, but did not solve my issue. My code is as follows: Public Sub AddToCart(ByVal s As Object, ByVal e As EventArgs) objDT = Session("Cart") Dim Product = ddlProducts.SelectedItem.Text Dim blnMatch As Boolean = False For Each Me.objDR In objDT.Rows If objDR("Product") = Product Then objDR("Quantity") += txtQuantity.Text blnMatch = True Exit For

I have found code that launches Mailto: the code is as follows: Public Function OpenEmail(ByVal EmailAddress As String, _ Optional ByVal Subject As String = "", _ Optional ByVal Body As Object = "") _ As Boolean Dim bAns As Boolean = True Dim sParams As String sParams = EmailAddress If LCase(Strings.Left(sParams, 7)) <> "mailto:" Then _ sParams

• Re: Display a shopping carts contents in a mailto: message

  thanks for the help. I actually do want to have the email launched on the client with what they selected in the cart. At the moment we do not want to have online processing only an email that is sent to us with the items that the customer is interested in. However, I do want them to be able to edit the message, should they wish. It also makes them more comfortable if the email client is the one they are used to. I hope this explains what I am looking to do. thanks, John

• Re: Display a shopping carts contents in a mailto: message

  I am able to accomplish this with the original code, what the real problem is getting the grid values into the body of the email so the customer does not have to copy and paste. Thanks,

• Re: Display a shopping carts contents in a mailto: message

  Understand! I can get both version of the javascript to work, however I still cannot get the data rows from the grid that I mentioned above into the body of the message. Thanks for your help.
