sending data from child gridview to parent gridview

[srishree]

I have a gridview with a link in the parent page.when i click on the link it opens up another gridview.this child gridview has 2 columns,one is a checkbox created using an itemtemplate and another a boundfield retreiving data from the database.what i want is when i check the checkbox of a particular row and hit a button,the data existing in that particular row of the child gridview which has been checked,has to transfer the data from that row to the parent gridview,in a sense the parent gridview has to refresh and show up with the new data that has come from the child gridview control.How can i do this?..........urgent..........
