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..........

Thanks for the reply.but it has not solved my problem completely.i have done similar to what u have replied,but in my case i need to loop through the inner cells of the gridview and as well the rows and check if there is a checkbox at any cell in the gridview,if exists,based upon my requirement i have to click the checkbox in those cells and also check the checkbox in the first column,and then update.what i want is to check the checkbox in the gridview cells and also the checkbox field created using the itemtemplate in the gridview.when i check the cells with checkboxes and then check the checkbox that is existing in the first column of the gridview and click the update button,then the data in the corresponding row should update.....
