Hi friends

 

how to solve the below problem

 

when I run the application I got an error like

 

Server Error in '/New/Application.

Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

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.

Answer 2

The problem with using email to sms is that most networks dont offer that service.
Most US networks do, but if you require international services, its not be best option.

The other option is to use an SMS Carrier which is generally able to provide sms services to most networks worldwide. Most provide free software which means you only pay a small fee for each sms sent.

We also provide reply services so that you can receive sms back into your system.

Hello:

For sending sending a simple sms message, the process is the same as is used to SMTP email; the address is set per the user's telephone number and the address is set up by the carrier.

e.g.:  [e-mail] (for Chennai RPG)

Take a look at this too:  http://www.c-sharpcorner.com/UploadFile/scottlysle/TextMsgToCellPhone12112006002339AM/TextMsgToCellPhone.aspx?ArticleID=334ff88f-7601-45f1-9dbc-82e004a5a9d3

(be sure to download the code for this one, it was recently updated)
