Rename exported PDF file in RDLC Report Viewer in ASP.Net

Mr.Mudassar 

I have an issue in report viewer export Receipt into pdf. I am using your code and at time export the file name comes based on pagename. Like Receipt.pdf

If i want send receipt to my customer, i need to include the receipt number like TE724785872/201503-2. user always do wrong enter the receipt number to store in the folder to send the customer later.

It is also very diffcult find receipt on time of sending to customer. We have to open one by one and check and attached in email. 

Is there any possible reportveiwer add receipt number automatically on time of export into PDF

(like TE72478/201308-2.pdf)

Pls advice me.

Thank you
