GridView1.DataBind(); ERROR

Question

Hello:
 
I found an article to help me get connected to MySQL. (Using MySQL for testing only. Will eventually use MSSQL). http://www.c-sharpcorner.com/UploadFile/iamibohal/339/Default.aspx
 
It has a line: GridView1.DataBind();
 
Seems that that .DataBind() is not right. Can someone tell me what it should be or what I am missing?
