Help Writing Codes in Class.

[hshah]

Hello All,

I have created a .aspx page with 7 text boxes and a save button. On click event following code is fired. It save the property information to sql server and also generate a unique Id for that porperty and fatch that id and show it on that screen. I have created a .cs file for TrustConnectionString as below.

Can someone please help me or guide me, is this a good practice to write code? If not can you please help me how to break this large code into classes or method and call them one by one.

Thanks for your help.
