I have 2 aspx pages. page1.aspx pops up page2.aspx.
Page2.aspx has a gridview with checkboxes. Page2.aspx also has an "Add" button.
When user clicks gridview's checkboxes and clicks "Add", I want ***PAGE1.ASPX*** to get the list of rowIDs (rows that were checked) from gridview.
Is this possible?? Is it possible for page2.aspx to communicate with page1.aspx when button on page1.aspx is clicked??
