Google Chart QR Code - Data is greater than 2k + Asp.net -

I am using Google chart QR code, I have to send data to more than 2k, I I read the document

It says that

  sign can be data data points (0-9), alphanumeric characters, binary bytes, data or keys Are there. You can not mix data types inside a QR code. The data should be UTF-8 URL-encoded. Note that the URL has a maximum length of 2, so if you want to convert to more than 2K bytes (reduce the other URL characters), then you have to send your data using POST. Can I sample any Google QR code -   
 
 
 You can do this as you type 2K  
  & lt; Form action = 'https: //chart.googleapis.com/chart' method = 'POST' runat = "server" & gt; & Lt; Input type = "hidden" name = "cht" value = "qr" /> & Lt; Input type = "hidden" name = "chl" value = "this is a test" /> & Lt; Input type = 'hidden' name = 'chs' value = '300x200' /> & Lt; Input type = "submit" / & gt;
