search using multiple fields on search button click in a dat

Question

I've a data grid view where I am showing all my rows from a table. I want to do search on this data grid view based on the fields

FromDate, ToDate, ReceiverName and AgentName on "search" button click.

When searched on net, I can only found examples of search as you type where there is only search field present.

Please guide me how can I do search using multiple fields on search button click in a datagrid.
