'Like' condition - MySQL -- Bind in GridView

Hi,
I want to make a stored procedure for the following task : Get records from 3 tables based on particular parameters using like command in MySQL. The parameters here, 'first name','last name','id','city','state','country','street'. Here, my procedure worked correctly if,it contains the data in database. For example, In database I've name "Rajkumar". when i search name like "Raj", it'll retry the data. But if i search the name, which is not present in database it'll show the error

The IListSource does not contain any data sources.

I also try to bind the datagrid within if(!IsPostBack){}. But there's no change
