How to update gridview records in other webform

How to update gridview records in other webform
 

Here we will first insert some records into an Insert.aspx page. After inserting the records the control will move to the Default.aspx page where we can visualize the records that we have already inserted. Here the first record will be displayed as a link. So if we need to update some values other than the first record, then we will click the corresponding record link and the control moves to the Update.aspx page. We can update the records with an update button or if we don't want to update the record then click the cancel button, so that the control will move to the Default.aspx page.
