I guess you should use the row command event handler of the grid, if I got you right:

OnRowCommand="RowCommand"

Then you can add a button to the grid:

<asp:LinkButton ID="LnkButton" runat="server" CommandName="setValue" CommandArgument='<%# Eval("id")%>'>Set value</asp:LinkButton>

And a method to handle it:

protected void RowCommand(Object sender, GridViewCommandEventArgs e)
  if (e.CommandName=="setValue")
    [do something with e.CommandArgument and close dialog]
