@Bala, For your first query .. Please try writing data using Global Send key or Global send key events, that should help.It looks like web page events are activated using manual data entry, but write stage is just asssigning data to the field.
I hope u dont have drop down list , if it is, u have to make path as dynamoc for writing the data./
For search symbol not getting clicked, one thing u can try is
1.Enter value in the search box
2.wait for 0.5 sec
3.Press enter using Global send key. This key should be sent to the text box where u have entered the text to be searched. For this you need to spy the text box correctly. Make sure key is sent properly.
