Send Data from Grid view via query string

 I have a grid view contain the data of customers ... cust_no in the first column and cust_name in the second column...

I created new column in the grid view to put button in this column, then i converted this button to template item

everything is ok till now.

i want when i press on the button call another web page called data.aspx so i wrote the following code in the click event of the button

Server.Transfer("data.aspx");

how can i change this code to call data.aspx and sending the current row value of the cust_no as a query string.

thanks 4 all in advance.........
